Hakone Yosegi-zaiku Secret Box This is a 12-step puzzle box. I have confirmed that the mechanism works correctly. It is made of wood, so there are some minor scratches on the surface from a few uses, but there are no major scratches or dents that would damage the pattern. I no longer have the instructions because I know how the puzzle works, but the Maruyama Bussan website, a Hakone Yosegi-zaiku specialty store, seems to have illustrated instructions. Original price: 7650 yen. Perfect for those who want to enjoy it at a good price!
