These are resin cabochon parts. They are round, with a rounded shape on the front and flat on the back with a sticker, allowing for adhesion. They can be used to cover illustrations, etc. I think there may be other uses as well. I would like to sell them to someone who will use them. They are transparent (clear), but due to the thickness of the resin, they appear slightly yellow, but as you can see in the 3rd and 4th images, they look clear even against a white background, so I have judged that there is no problem. Basically, they are covered with plastic to prevent dirt and scratches, but some have come off easily (currently, 1 set (2 pieces) have come off and could not be reattached).
