Tamagotchi: Found at Sea! Clear and Blue

Found it at the sea: a Tamagotchi!
The pattern was unusual and it was cute back then.

I think I used it once, or maybe not at all...
My memory isn't clear.

The back is clear so you can see inside, but there's nothing particularly concerning.

I haven't checked if it works, so I can't accept returns or complaints if it doesn't.
