It's convenient because it can be played with USB! Batteries can also be used! I had it displayed in the living room for about two months, but I no longer need it due to a change in interior design. I hadn't moved it much, but I have checked its operation for the listing. Includes 10 dedicated coins, a USB power cord, and instructions. The return may be slow depending on the position of the wiring in the moving parts, but it can be fixed manually. It's just a toy, so please understand that the construction is not perfect. I remember buying it for around 7000 yen.
