This is a Hoppe-chan Suikore I bought over ten years ago. I stored it without using it much, with the batteries removed. There's a faint mark left on the back where a sticker was placed. I've confirmed that it works, and it functions without any problems. Also, because the screws were stripped, I bought replacements of the same size at a hardware store, and I'll include them with the item. *Instruction manual and box are not included. #Hoppechan #Sunhoseki #Game #Suikore
