Here is a full set of Segaprize keychains. These are rather large (for a keychain) and made of die pressed/cut flexible rubber. It's the same stuff the older USA keychains were made of, which holds detail quite well, and is layered. You can get Knuckles, Tails, Sonic, Silver, Shadow or Amy Rose. They were produced for the 20th Anniversary (as seen with the logo on everyone's card) You can sort of see their lead-loop at the top of the card. These feature new poses that weren't issued on previous rubber keychains. A nice set! Sometimes find-able on ebay. Were these a UFO prize?
