Thank you for viewing! These are socks manufactured by our company. These socks are made with a soft fabric on the outside and silk on the inside. From the opening to above the heel, the inside is a "pineapple knit," which creates layers of air, adding dimension and thickness. The thickness is about 2 cm from the opening to above the ankle, and about 1 cm in other areas. Because the socks themselves are thick, they don't feel cold even in cold weather and are comfortable to wear for long periods. You can wear them after a bath, when you go to bed, or for everyday use. - Size: Length 18-20cm Foot length: Free size (up to about 26cm) - Color: Orange - Design: Plain - Materials: Outer: Rayon 66%, Nylon 34% Inner: Silk (Tsumugi thread) 100% Product photos are adjusted to match the actual colors as closely as possible, but they may appear slightly different from the actual product depending on your monitor environment and the lighting during photography. Please understand this beforehand. How about a pair for the coming cold season?
