Kimetsu no Yaiba Seal Wafer ・Kocho Shinobu Ultra Rare ・Iguro & Kanroji & Tanjiro Normal Only sold as a set, individual sales not available. After opening the product package, I have wiped the surface of the bag containing the seals. As mentioned above, I have wiped them once, but due to the nature of the product, there may be some remaining wafer residue, powder, or odor. The seals themselves have not been removed from their bags and are unopened. Please consider the above before purchasing.
