These are round stickers. They are fairly large, likely at least an inch across, so they're all right for decorating things like notebooks, boxes or binders. They're just basic round stickers with finger-waving Sonic in a gold ring behind the title-screen style 'Sonic' banner. The text around the gold ring (it's hard to read, and part of it is always covered by the art) says "His Name is Sonic" in English, although these stickers were a Japan only release item.
