The whole thing is silver. There's germanium on the back. It's a magnetic bracelet. It's also said to bring good luck, as it features nine horses (Kuzuryu). I didn't know when I listed it, but that's what I was told by the person who bought it. I've changed the price. I apologize to those who were watching! The size as is measures 18.5 cm. However, the inside is elastic, so it can stretch and fit over your wrist! It fits snugly.
