It was quite expensive when I bought it. I think it cost around 100,000 yen. Since it's an old item now, I don't have the warranty or instruction manual. There are scratches because it was used. Small diamond chips are embedded. It has some weight. We do not accept returns or complaints after purchase, so please purchase with your understanding. Please be sure to read my profile as it contains important information regarding transactions. Shipping will be via YuYu Mercari便. #Germanium #Health #Bracelet
