Thank you for viewing! I am selling Cogit's room socks, Bincho-tan Home Socks Ankle Long. This is a new, unused item. The color is dark gray. 【Contents】 ■ Double-layered construction for extra warmth! 　Bincho-tan Home Socks Ankle Long from a long-established sock manufacturer ■ Compatible size 　22.5 - 25.0cm ■ Materials ・Outer: Acrylic, cotton, nylon, rayon, others ・Inner: Acrylic, nylon, wool, synthetic fiber (acrylate-based), others 【Product Description】 Introducing the extra-thick home socks <Ankle Long> that completely wrap your ankles and keep you warm, perfect for relaxing at home. The key feature is the double-layered construction. This creates an air layer, making it easier to retain warmth. "Toyobo Co., Ltd." yarn is used in three inner areas (toe, heel, and calf). Bincho-tan fiber is used throughout the outer layer. Non-slip grips are attached to two areas on the sole (toe and heel). The shape makes it easy to put on by pinching. The pile-knit construction provides a comfortable fit with less constriction and leaves fewer marks. This is a carefully crafted, made-in-Japan item produced by a sock manufacturer with over 100 years of history.
