This is a paperclip holder. That cylender thing has a magnet inside, which attracts the paperclips so they lay all over it, & on the round base. It was obviously produced to promote Sonic 2, & uses the slightly less-common "Tails peeks out from behind the number" art for it. A paperclip holder is kind of obscure, this is likely the only Sonic themed one done.
