Tamagotchi m!x Melody m!x ver. Blue There is some blackening on the part that is pressed when changing the battery. This is the main unit only, without the box or instruction manual. Batteries are not included. Operation has been confirmed. I bought this when I was in elementary school. Since it was played with, there are scratches and dirt on the screen, etc. Please check the images and purchase only if you understand. Immediate purchase is OK. I will respond to price reductions within a reasonable range, so please comment if you have a request. Thank you for viewing.
