Chou Keitai Kai! Tamagotchi Plus This item was purchased and played with in the 2005 era. There is yellowing overall, scratches on the screen, and sticker residue. I turned it on for a few minutes to confirm, and I believe the screen display and buttons are both working fine. Due to its age, please refrain from purchasing if you are concerned. I will also include the buttons used for the operational check.
