I don't know much about the tea ceremony or teacups, but this is something I received as a souvenir. It has a painting on it that looks like it was done with ink, so it's also good for display! I don't know if it's been used, but it's very clean. I think even if it was used, it was probably just for display. It has a presence with its teacup shape, just like a tea utensil.
