These Jewelpet stickers were purchased at Sanrio Puroland about 10 years ago. I've already used some of them. The Little Twin Stars stickers were purchased a long time ago, but the exact date is unknown. They have been used, and only a few remain. Suitable for collections, etc. They have never been peeled from the backing sheet, so I think they still have adhesive, but they are stickers that have been stored for a long time. Please refrain from purchasing if you are concerned about used items. I am also selling other stickers. If you would like to buy multiple items, I will offer a discount, so please feel free to contact me.
