This is a "Tamagotchi 3-piece set, junk item." No instructions or packaging are included. I bought and played with these approximately 30 years ago. All three screws are stripped and cannot be opened. Therefore, I don't know if they work or if they have batteries. There is some sun fading, sticker residue, and scratches from trying to pry them open due to the stripped screws. They will be placed in an OPP bag, wrapped in bubble wrap, and shipped via anonymous Mercari delivery. Returns and exchanges are not accepted to prevent swapping. Please consider purchasing after understanding and agreeing to the above. - Colors: White, Blue, Purple - Type: Digital Pet - Quantity: 3-piece set - Design: Egg-shaped - Function: Raising game - Accessories: With chain - Number of buttons: 3
