Bonbon Drop Seal Style 3D Puffy Stickers This is a set of 6 different types of stickers, 6 pieces in total. They are made of hollow plastic. They are slightly inferior to the real Bonbon Drop Seals, but they are very cute ^ ^ My elementary school daughter is very satisfied and can use them as much as she likes. These are imported products, so please refrain from purchasing if you are looking for perfect, authentic Bonbon Drop Seals. Photos 2-4 show the actual product. No claims and no returns, please.
