If you're hunting for boxers and swim briefs on 1688, 义乌市浣歌电子商务商行 is one of those small shops that flies under the radar. Only 26 items listed, but they've got a bit of a cult following – one guy even called their Iron Man boxers "tuff ass psd boxers" and said the quality is solid. Not exactly Shakespeare, but that's the kind of raw feedback you want when buying unbranded undies. The store rating is a perfect 5.0, though it's only backed by one review, so take that with a grain of salt.

On the logistics side, they're quick. Dispatch time averages 0.4 days, and domestic shipping to your agent's warehouse clocks in at just 1.3 days. That's the time from seller to the local Chinese proxy warehouse – not your doorstep, just to be clear. So if you need your package hitting the warehouse fast, these guys deliver.

Their top saved items are Iron Man, Boxer Briefs, and The Staple – all in the Swim & Intimates category. Zero defect records, which is promising for a smaller shop. The only downside? With just one review on the books, you're flying a bit blind. Could be a hidden gem, or you might be the guinea pig. If you're after a no-frills, fast-shipping underwear seller, give 'em a shot – just don't expect a ton of social proof yet.
