Second photo: First-generation Tamagotchi Window Decos I cut them out one by one and collected them. They are not a complete set, but I kept them with care. I haven't peeled them from the backing, so I'm not sure about the adhesive strength. They are not paper stickers, so they are perfect for sticking on windows, tiles, phones, etc. Ninth photo: The shape is such that it can't be peeled off the sheet. (It might be the type that you apply with water) I forgot how to use them, but they were cute, so I'll put them up for sale together. All are vintage stickers. Please understand that there may be age-related deterioration before purchasing.
