This is the nostalgic Perfect Mahjong 2. It requires 2 AA batteries. There are minor scratches from use, but I think it's in good condition for something that's 40 years old. There's also no smell of nicotine, a common problem with items from the Showa era. The following has been confirmed: Battery compartment: Good condition Power: Starts up without any problems Sound: No problems Screen density adjustment: Adjustable without problems Tobacco smell: None Button damage: None Accessories: Original box and instruction manual included Bandai BANDAI Perfect Mahjong Perfect Mahjong Mahjong Mahjong Game console Retro Vintage
