I had no idea what "market seal bits" were, but turns out, they're stickers. These are clear stickers of sumikko gurashi. They're quite small (about the size of my thumb nail) and since they're not adhered to a sticker sheet, they can get quite finicky when you try to use them. There's no convenient slit in the back for when you want to peel the sticker off its backing, since it's so small. But it's still cute and the quality of the stickers is good.
