An anklet made of approximately 6mm terahertz and black silica balls. Mainly terahertz, it's good for cold feet when worn on both ankles. Please measure your ankle with a string and let me know the size. Women's sizes vary from 16cm to 25cm, so please measure your ankle. Different sizes are available, and sizes over 25cm are 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 Scratches/Discoloration: None
