Brand new, unused. I think it fits sizes 22-25 cm. It's a very good item made of soft cotton that keeps your feet clean with insect repellent and antifungal effects. Opened for photography. Between the big toe and the second toe, there are acupressure points like "Taisho" that are effective for coldness and hot flashes. Stimulating that area improves circulation throughout the body. Reduces the burden on the knees and lower back.
