Dongguan Humen Canlin Kaini Intimate Apparel Factory

If you're hunting for solid basics on 1688, this Dongguan seller is a low-key gem for men's underwear. They're sitting at a perfect 5.0 rating across 27 products, and the standout item is clearly the Modern Cotton Trunk. The sizing advice is spot-on, and the feedback consistently mentions good fabric and a comfortable fit. One buyer even noted the label and stitching feel premium for the price, which is exactly what you want to hear when ordering through an agent.

Shipping to your local Chinese proxy warehouse is quick—averaging just 1.4 days, with dispatch happening in about 1.2 days. That's fast for domestic transit, but keep in mind this is only the leg to the agent's warehouse, not the final international hop to your door. The other top-saved pick is the Cotton Stretch Low Rise Trunks, so the catalog is tight and focused on intimates.

Here's the honest part: there are only 4 total reviews, and zero defect records. No red flags, but also not a massive track record. If you want a quick, reliable add-on for your next haul and you're cool with a smaller review pool, this seller is a safe bet. Just double-check your size against the chart because returns aren't worth the hassle.
