We thought that having something to replace “Have a good day” and “Welcome back” could bring a bit of fun and richness to everyday life.

We designed an item that you can stick anywhere you like and insert your key into. When you go out, KEAT becomes expressionless, but when you come back and insert the key, it smiles. When people smile, their teeth show. KEAT provides that little trigger for such a smile. It also comes with a key for KEAT in case your own key doesn’t fit.
