New colors of ``Material and Color Short'', thin socks with a two-layer structure knitted with 100% silk on the inside that touches the feet and 100% cotton on the outside, are now in stock! Luxurious pile knitting of high-quality silk. Not only is it comfortable for your feet, but the increased surface area quickly absorbs sweat and waste products and releases moisture. These socks allow you to feel the slippery feel of silk against your skin. We hope you enjoy matching it with your clothes. Please see the product page for details.
