Mitsuo Aida teacup and mug/cup (Yellow Hat, not for sale). This is a set of two and cannot be sold separately. Although it is new and unused, it has been taken out of the box for photography. It is thick and quite sturdy, and it seems like it will hold a lot. How about it for the coming cold season? Thank you for viewing. ● Mitsuo Aida teacup and mug/cup (Yellow Hat, not for sale) ● It is quite sturdy. It seems like it will hold a lot. How about it for the cold season?
