An anklet made of approximately 6mm terahertz and black silica balls. The main component is terahertz, and wearing it on both ankles is good for cold feet. Please measure your ankle with a string and let me know the size. Women's ankles can range from 16cm to 25cm, so please measure yours. Different sizes are fine, and for sizes over 30cm, it's an additional 200 yen per cm. Genuine terahertz makes a difference, even with just one pair of socks. If you want to make your own, I also sell a set of terahertz beads and operon rubber. #Terahertz #BlackSilica
