I have stored this item in a dark place since opening it. Please refrain from purchasing if you are concerned, as it has been stored by a private individual. т ̫ т I will apply waterproof processing and wrap it in bubble wrap (the coaster will have cardboard reinforcement on one side) before shipping via Yu-Packet Post Mini. Immediate purchase is OK (＾_＾)❤︎ Jujutsu Kaisen Exhibition Battle Coaster Name Badge
