These are the Tamagotchi's 1st-anniversary commemorative, not-for-sale Ossu and Messu. I found them while cleaning up. They have been stored for many years, and the main unit has not been opened, so I have not confirmed their operation, but they have been stored in the box the whole time and are in very beautiful condition. The box is slightly yellowed. Please understand this. Immediate purchase is possible. Please also take a look at my profile. Tamagotchi's first-anniversary special edition, blue and pink color variations. - Product Name: Tamagotchi - Colors: Blue, Pink - Commemoration: 1st Anniversary - Special: First Anniversary Special Toy Genre...Family Toy/Game
