Here's a great keychain that could only be bought from Segaworld Australia (while it existed). It is silvertone metal with colored enamel for the oval and all 3 characters. Sonic's in front, with their slightly browned Tails to one side & aggrivated (as usual) looking Robotnick on the other. (though he's just squeezed in there) What's extra interesting is, that it came with a plastic case. It's clear, with yellow & black checker stripe, and some rings scattered over it. The bottom photo shows what it looks like when you put the keychain in there. This is uncommon.
