We all have those friends (or maybe even people who live with us) that love staining the table with glass marks. Now you can be honest in a funny way. Perhaps it is a little passive-aggressive but still in a polite manner. With these coasters, you will leave the message clear, and people will leave your table clean.
So much mixed emotions .. from sweet and tame it turns into a dangerous and angry koala. Who will actually know the right attitude? It will be a super fun gift for any kid.
