I've kept this stored in a dark place since opening it. I left it untouched, with the cardboard inside still in place. I've never used it, so it doesn't show much wear, but there's a brown discoloration on the cover, possibly due to a stain or a manufacturing defect. Please be sure to check the photos and only purchase if you understand this. #Kuromi #KuromiOshi (Kuromi fan) #KuromiGoods #Sanrio #SanrioGoods #SanrioCharacters #MyMelody #ZaraiKei (Landmine Style) #RyousanGata (Mass Production Style) #OshiKatsu (Supporting your favorite)
