China Exclusive Sanrio Licensed Product This is an authentic product. Kuromi 2-piece set These are 3D立体 stickers with a solid feel, not hollow. I bought them as a set and put the same ones in my sticker book, and they are super cute!! This is a rare item that isn't widely available. Although these are China exclusive authentic products, some may have printing errors as they are made overseas. I have checked them myself and found no particular issues, but please understand this before purchasing.
