However, these threads are not defective; they strengthen the structure of the toe socks and help to keep the socks durable. We advise leaving them as they are since cutting these threads may cause holes and weaken the integrity of the sock.Made in JapanMaterial: Wool 84%, Nylon 15%, Polyurethane 1%Women's Wool SocksWomen's Tabi (Big-Toe) SocksWomen's Signature Collection* The actual colors may look different from the colors in the pictures depending on your monitor, browser, the color of light, Illuminance and view angle.
