Size: 26.0 cm Color: Listed as blue on the site, but also looks gray. Material: Mesh Retail Price: 3,099 yen I purchased these around July of this year, but I'm selling them because they don't suit me. The opening is soft, and the material allows for a relaxed fit, like wearing socks. The original box is not included. Although this is a new item, please refrain from purchasing if you are sensitive to items stored at home. Returns and claims are not accepted. Please feel free to comment if you have any questions!
