I just got this at Kura Sushi! I won't be using it, so I'll give it away if anyone wants it. It will be waterproofed and sent anonymously in a 3cm cardboard box. It's a new, unused item, but since it has been handled by a person, please refrain from purchasing if you are sensitive to this. I am also selling BT21 napkins separately, If you would like to purchase those as well, I will include them for an additional 300 yen, Please let me know in the comments section before purchasing.
