Alright, let me break down this 1688 seller – 广州天纳服装商行. They’re a small player with only 21 products, mostly in swim & intimates plus a few bags. Ratings look flashy (4.9), but I dug into the numbers and recent reviews. Here’s the real talk.

What They Sell
Mostly underwear and swim trunks. Their top-saved items are *Modern Cotton*, *Trunk*, and *HeatGear* – basic everyday stuff, nothing fancy. They also have a *Greca Border* item (some sort of waistband or accessory?). Small catalog, so you’re not drowning in choice.

Warehouse Delivery Vibe
Average dispatch time is a snappy 0.4 days, and total delivery to your Chinese agent’s warehouse sits at 1.0 day. That’s quick – domestic shipping inside China is basically a breeze. But remember: this is the time from seller to your proxy warehouse, not to your doorstep internationally. That part is on your agent.

The Good

Zero defect records in the data – clean record on that front.
Sellers rating is a solid 4.9, and dispatch is lightning-fast.
Reviews for *Modern Cotton* are mostly positive: people dig the soft, breathable fabric, and they say it holds up after washes. One Italian guy called it “mutande belle” (nice underwear). A Spanish buyer said quality and sizing were spot-on.

The Bad (Be Honest)

Only 20 total reviews – that’s a tiny sample size for a shop claiming 4.9. Take that rating with a grain of salt.
The *Greca Border* product has three identical reviews (copy-pasted word for word). That screams fake or lazy feedback. Not a red flag on quality, but definitely on trustworthiness.
The *Trunk* review mentions the fabric is thin and the inside tag can be annoying (easy fix cut it, but still).
Several *Modern Cotton* buyers warned to size up once or twice – so if you’re between sizes, don’t assume true fit.
For a 4.9 shop, the overall review count is low. Could be a newer store or only a few loyal customers.

Bottom Line
A tiny shop with fast warehouse shipping and decent product reviews, but the fake-looking reviews and sizing quirks are a caution. Worth a punt if you’re after cheap basics and don’t mind rolling the dice on fit. Not a top-tier seller you’d blind-buy from in bulk.
