The tamagotchi is missing the keychain.  The hole for the keychain is damaged on the back but could be glued to reinforce it.  I purchased a replacement screw for the back.  It fits well.  The pattern looks like japanese iris in orange, pink and purple.  The shell is an aqua teal color.  The battery terminal is clean.  It uses a 3V round battery to power it.  I do not ship electronics with batteries.  I tested the toy and it works.
