This is a set of three toe separators. Made of silicone, they can be washed with water or lukewarm water and used repeatedly. By widening the space between your toes, blood circulation improves, and beauty benefits can be expected. Also effective for cold sensitivity. Furthermore, they are effective in preventing and improving bunions, tailor's bunions, and flat feet. They are also convenient when doing your nails. *It seems long-term use is not recommended. Thank you for looking!
