This is a set of two sheets of Kuromi's Bonbon Drop stickers, not sold in Japan. The stickers are not hollow, but a hard type. These are overseas authentic products from Alifish (阿里魚), which has a license agreement with Sanrio. Sold separately for 850 yen each. ※Please note: There may be printing misalignments, variations in adhesion, and package folds. Also, the product management code sticker was originally affixed to the back of the backing card, but it has been removed to confirm the license authentication. There are traces of removal, so please be aware of this. If you are concerned about minor details or are looking for a perfect product, please refrain from purchasing. m(_ _)m #OfficialLicense #AuthenticProduct #Uruturu (glossy/smooth) #BonbonDropSticker #HardType #3DSticker #ThreeDimensionalSticker #PukpukuSticker (puffy) #Bondro (short for Bonbon Drop) #Bonbon #StickerExchange #RewardSticker #Kuromi #Sanrio #Sticker
