Well this is what the item description says...
This is NOT A virtual pet.
It is a Tamagotchi Game that is manufactured by Ban Dai, the same company that manufactures the Tamagotchi's.
It HAS been opened by me ONCE. However, it is still in original packaging, with original instructions.
This makes a great item for collectors of Kawaii (cute!) Japanese items. Really cute!
I think that pretty much describes this item: a type of video game that never got released here. I'm curious to see what games are on there and how you play them.
