This is a collaboration mug between Lawson and Demon Slayer from February 2022. This is Type B (Giyu, Shinobu, Kanao, Tengen). It's a cup that originally contained jelly, but it's unused as the jelly was not directly in contact with the cup. It will be shipped with simple packaging. Please refrain from purchasing if you are concerned, as this item has been stored at home for a long period of time.
