Opened, but it's a new, unused item. It will be shipped via postal mail. Color: Mint Body size (approx.): [Total length] 49cm [Width] 9cm Type: Ladies Material: 65% Polyester, 28% Nylon, 5% Acrylic, 2% Polyurethane Warm feet all day long ♡ Excellent socks, a must-have for winter! Attention, those who feel the cold! SOL FIBER® Uses "Sol Fiber®", a heat-absorbing and heat-generating material that gently warms with the power of sunlight and far-infrared rays. High-density carbon particles contained in the fibers absorb sunlight (infrared rays, visible light, and ultraviolet rays). By repeatedly absorbing and radiating sunlight and body heat, a heat cycle is created, and the warmth and comfort last throughout wear. The "core-sheath composite fiber technology" is used, where the fiber structure consists of two layers: a core and a sheath. By kneading carbon particles into the core, the heat generation and heat retention performance lasts semi-permanently even after repeated washing. Suppresses static electricity "crackling" and makes it comfortable to put on and take off. * Static electricity from external factors (doorknobs, car doors, people, etc.) cannot be prevented. Highly elastic and gently fits the entire foot. When worn, there is a slit in the instep, and by exposing the toes from that part, heat and moisture are less likely to build up. Pulling up the sock part turns it into a leg warmer. Since there is no heel part, it can be worn by women and men. You can use it when relaxing at home or during bedtime. ・Combined "Sol Fiber®" with "Tactel Mole", a material characterized by a marshmallow-like soft touch. Furthermore, by knitting with "Whole Garment®", there is less irritation to the skin, and it is a stress-free 2-WAY sock even with long-term wear. Recommended for bedtime. ・When worn, there is a slit in the instep. By exposing the toes from that part, heat and moisture are less likely to build up. ・The socks can also be pulled up to become leg warmers. ・Since there is no heel part, it can be worn by both women and men. ・Conductive carbon particles suppress the generation of static electricity. Suppresses static electricity "crackling" and makes it comfortable to put on and take off. * Static electricity from external factors (doorknobs, people, etc.) cannot be prevented. ・The brand name uses a suede-like tag, paying attention to the feel against the skin.
