Mianxiaoniu Pure Cotton T-Shirts

• Reference Price: ¥18

Friends, I’ve finally found the ultimate cheap-and-good T-shirt.

A while ago, I got rid of a bunch of T-shirts that I’d been wearing for years or that had already lost their shape, so naturally I needed to restock. During my search, I came across this store. Originally, I was buying their shirts with the mindset of them being disposable basics — something you wear a couple of times and toss away. But the quality turned out to be surprisingly good, far beyond my expectations, so I absolutely have to rave about them in this edition of New Stuff.

Their T-shirts use a very standard, versatile cut, and even the 320g version already feels quite thick and substantial while still being soft and comfortable to wear. I bought several colors including Klein blue, forest green, navy, and gray, and every single one looks vibrant and well-saturated rather than cheap. What’s even more impressive is that despite being heavyweight pure cotton shirts, they barely shrank after washing and don’t noticeably fade. In terms of quality, I genuinely have no complaints. At first I was planning to try their 400g version too, but after wearing the 320g one, I realized there was really no need — it’s already soft enough while still feeling durable.

Another advantage of these blank-style T-shirts is that the fit is basically unisex. Personally, I prefer wearing oversized clothes, so I bought one size larger than the store recommended. Considering how cheap these shirts are, even if you don’t wear them outside, buying a few oversized ones as sleepwear at home is honestly not a bad idea.

The colors from this store are all lively and vibrant without looking tacky at first glance. It feels like they’ve actually done market research and understand younger people’s preferences. Their main product is clearly these blank T-shirts, though they also sell sweatshirts, hoodies, and similar basics. The whole store really does look like a factory-direct operation. It’s a shame they don’t sell athletic pants, otherwise I’d probably stock up on several pairs too — definitely more reliable than randomly buying from different stores and platforms.

Another benefit of the low price is that if you’re traveling, you can buy several shirts in different colors and wear a different one every day. It would probably make vacation photos more fun too.

Given how developed China’s apparel manufacturing industry is these days, there are probably tons of similar stores on e-commerce platforms. I’ll leave a link here so you can jump directly to it, though you can also expand your search based on your own preferences. In any case, from a practical standpoint, these cheap, simple white-label T-shirts are already surprisingly comfortable to wear and are perfect for stocking up on ahead of summer.

Bambu Lab X2D 3D Printer

• Reference Price: ¥5099.15 (Multi-Color Printing Bundle)

Good grief, Bambu Lab had barely finished launching the Bambu Lab P2S before the Bambu Lab X2D arrived. Even though my few months with 3D printing have been very much “lazy user” territory — I mostly just print models made by other people and almost never touch parameter tuning — I still brought the X2D home immediately.

The overall design and performance of the X2D are not dramatically different from the P2S, and many parts are even interchangeable, so I won’t repeat the basic printing experience here. If you’re interested, you can check out the P2S write-up I previously shared in New Stuff:https://sspai.com/post/105458

Compared with the P2S, the X2D mainly adds several key features. First, it now has two print nozzles: one primary nozzle and one auxiliary nozzle. To reduce the size and weight of the print head, only the primary nozzle is equipped with an extruder mounted directly on the head, while the auxiliary nozzle’s extruder becomes a separate external module. Under this “remote extrusion, close output” structure, the two nozzles have slightly different printing characteristics. The primary nozzle uses a servo motor for extrusion, while the auxiliary nozzle uses a stepper motor, meaning the primary nozzle supports a wider range of materials, offers finer detail control, and achieves higher printing efficiency.

Secondly, the X2D adds an active chamber temperature control system, allowing it to print a wider range of engineering-grade materials. The machine now includes dual air intake ports, enabling chamber temperatures to rise and fall faster and more accurately than on the P2S. On top of that, the X2D also comes bundled with an external air purification module. This upgrade works alongside the chamber temperature system to reduce odors during high-temperature printing.

So, you can basically think of the X2D as the Pro version of the P2S. It still handles everyday printing needs effortlessly, while also giving you room to experiment with industrial-grade materials and more product-oriented creative projects.

From actual day-to-day use, I mainly noticed two things. First, dual-nozzle printing dramatically simplifies support structures. For example, my primary nozzle is connected to the AMS and prints only PLA, while the auxiliary nozzle is dedicated to PETG. This creates excellent separation between the support material and the main print, making supports incredibly easy to remove without carefully picking at them with tools for ages, which saves a ton of time and effort. Second, the active chamber temperature system noticeably improves print quality. I previously encountered warping issues at certain angles on some models when using the P2S, but those problems disappeared entirely on the X2D.

Overall, if you want a 3D printer suitable for home use, the Bambu Lab X2D is already about as high-end as it gets. For users like me who mostly want to print finished products to solve practical daily-life problems, Bambu Lab’s biggest strengths remain the same: easy setup, reliable operation, and consistently solid print quality. For users who want to seriously explore 3D printing, run projects, or even start a print farm, the X2D’s performance is also strong enough to satisfy most needs and creative ambitions.

Oh, and Bambu Lab recently introduced a new material called PLA Pure, which focuses on food-grade safety and can supposedly be used for items like tableware and children’s toys. This is actually a material I’ve been waiting for for a long time — I’ve wanted to print a food bowl for my cat for ages. I already received the new filament but haven’t started using it yet. If I have any thoughts after trying it out, I’ll write a follow-up later.

@怡宝：OASEAR Witch Pro HiFi Earphones

• Reference Price: ¥522

A warm-toned anime-style IEM

I originally approached this with a simple mindset: if I’m just buying something for commuting and casual listening, it at least has to look good. That’s how I ended up getting the OASEAR Witch Pro. Honestly, the first thing that caught my attention was the pink “Taoyao” model from the same lineup, but after debating for a while, I decided I wanted to try the upgraded “Witch” version instead.

Appearance

The “Witch Pro” uses a dark purple semi-transparent resin shell with a very smooth and refined texture. Comfort and lightweight design both deserve praise. Personally, I prefer integrated in-ear designs, and these didn’t cause any ear pressure even after wearing them continuously for two hours. I used the smallest included ear tips, and they still didn’t press against my relatively flat ear shape, so I’d say they’re friendly for people with smaller ears.

Listening Experience

Since these are clearly vocal-focused ACG earphones, I started testing them with 茜さす by Aimer. Aimer’s slightly husky voice pairs extremely well with the warm tuning of these earphones, fully conveying the sorrowful “crying voice” quality in her singing. The indescribable loneliness in the lyrics somehow gains an unusual sense of warmth and healing here. Once the strings enter, however, one limitation caused by the earphones’ resolving ability becomes more noticeable: the separation between instruments is not especially sharp, but in exchange, the overall presentation feels more enveloping and immersive.

Next, I listened to 夜に駆ける by YOASOBI. The “Witch Pro” really shines with smaller arrangements and vocal-focused tracks. When things get busier, instrument separation starts struggling a bit, with bass and synth layers occasionally overlapping. The high-frequency extension is still fairly good though — violin overtones retain an airy feeling without sounding harsh, and most importantly, the vocals never get buried. Comparatively speaking, the “Witch Pro” feels much better suited for solo vocal and ethereal-style ACG tracks rather than extremely noisy electronic-heavy anime music.

As someone with fairly broad music tastes but a preference for soul and R&B, I also listened to The Show Must Go On by Bruno Major. The balance between vocals and accompaniment was handled nicely, with soft drum hits and an intimate close-to-the-ear vocal presentation that fits the song’s emotional atmosphere of confronting regret.

Other Notes

The “Witch Pro” has an impedance of 20Ω and can easily be driven directly, though the volume output is surprisingly high, so I usually keep it at around half my normal listening volume.

For daily use, I pair it with the Moondrop Dawn Pro dongle DAC from Moondrop connected to my phone. It supports both 3.5mm and 4.4mm outputs with dual decoding, and at a little over ¥200, the value for money is excellent.

Final Thoughts

The “Witch Pro” uses a hybrid configuration with one dynamic driver and one balanced armature driver. While the treble is not especially bright, the bass extension goes deep enough without becoming overwhelming. Its real strength lies in the midrange, which sounds smooth, warm, and delicate. Emotional expression in love songs comes through especially well, making it a great fit for listeners with broad music tastes. Overall, this is a warm, atmospheric, and airy pair of earphones that delivers a very “ASMR-like” listening experience.

@巴斯: Decathlon TILT 120 folding bike

• Reference price: ¥1299

I recently picked up the Decathlon TILT 120 folding bike and have been riding it over the past few weekends. My takeaway: it may not be perfect, but at around the $200 price range, it’s probably the best value folding bike you can get—and one of the most suitable options for getting around the city.

From placing the order to having it delivered, it only took a day and a half. The bike comes in a large box and requires almost no setup—just unfold it, lock the “joints,” and you’re ready to ride. It truly delivers on the promise of “buy and ride.” As a beginner cyclist, I dislike complicated assembly, and anything that delays getting out the door quickly drains my enthusiasm. This bike is incredibly easy to get started with, which is one of the main reasons I chose it. It uses a classic mid-fold design, and the process is very smooth:

1. Release the hinge in the middle of the frame
2. Fold down the handlebar
3. Bring it together and secure it with the magnetic latch
4. Go

After trying it multiple times, I can confirm it’s easy to unfold within 30 seconds as advertised. Once folded, it fits easily into a car trunk or a corner of a café. Whether it’s short cross-city trips or a casual ride out for coffee, you don’t have to worry about theft, and it doesn’t take up much space at home either—very convenient for storage.

As for the riding experience, despite its compact appearance, the bike weighs 14.5 kg. The high-carbon steel frame gives it a reassuring heft, making the ride more stable while also providing some shock absorption. Going over speed bumps doesn’t feel overly bumpy.

The 560 mm handlebar width offers a comfortable reach for my arms. Although the TILT 120 sits at the entry-level end of folding bikes, it comes with a 6-speed gear system. It may not sound like much, but it’s more than enough for urban riding. I usually stay in gear 4 for flat roads, shift to gear 2 for uphill sections, and gear 6 when going downhill. Overall, the performance feels stable and gives me a strong sense of control and safety.

So far, I’m very satisfied with it. I mainly wanted something for casual weekend rides, but it turns out to be suitable for many scenarios. If you’re tired of the hassle and cost of shared bikes, or fed up with crowded subway rides, you might want to give this kind of healthy and controllable way of getting around a try—the scenery along the way might just quietly heal your entire day.
