Silk is a healthy material with protein as its main component and containing 18 types of amino acids. It is perfect as underwear. We've also started selling the #135 Night Beauty 100% Silk (main body) gloves, which you've been waiting for. If socks were truly made from 100% silk or 100% cotton, they would end up being tubular and loose. Some elastic is in the body and opening, but that is 3% polyurethane. Also, since the polyurethane is in the middle of the weave, the part that directly touches the skin is definitely 100% silk. Generally, the elastic part that doesn't touch the skin is exempted, and products are often labeled as 100% silk or 100% cotton, but truly 100% products cannot be sold.
