I have been buying Jinshi underway through Amazon for about two years now. I've purchased various styles and never been disappointed. The price is right, the quality superb and the packaging let's you know you've purchased quality. The bamboo fiber material fits like a glove just make sure you buy one/two sizes larger if you are not Asian. The group of bottoms I just purchased are the most comfortable yet. The colors and fit are perfect! I recommend Jinshi to any male who values how they look in underwater. Wish they made a thong too.
