Here are 2 Sonic figures. They're fully 3D, but one was used in some instances as a keychain (Sonic who snaps onto base with his name) & the other which is always a keychain (Arms crossed 1 finger Sonic) The base one was a SA1 era release, and other characters like a Chao, also appeared on the line. The other is simply a Sonic figure with loop on his head for the beaded key ring chain to attach. Both are well sculpted & nicely painted, perfect to collect. (And proof that a good job can be done, even on something that's pretty small, as shown by the ruler here in the photos.
