This is a Cuboro keychain. I received it at a toy store several years ago. I think it's a rare item that you don't see very often. I've marked it as "slightly scratched," but it's only that the logo might be slightly faded. The hole is also properly made. I've placed masking tape for size comparison. It's 2.5 cm. I think it would be cute to see it together with a mini Neffspiel keychain.
