I believe these are stickers that were sold in gachapon machines during the best-wisher era of Pokémon. I've attached a reference image from when I looked them up at the end of the photos. The items are only 19 stickers, so please make sure you understand this. There are no noticeable scratches, but they have been stored by a private individual, so please refrain from purchasing if you are sensitive to this.
