3D sticker set featuring Cinnamoroll, Kuromi, Hangyodon, and Pompompurin. They are solid, not hollow. I think they're perfect for children to play with. I purchased these, but I'm selling them because I haven't had a chance to use them. ※ Although it says "Bonbon Drops," they are not official merchandise and are made overseas. Please be aware of this before purchasing. Thank you for looking.
