Here are 2 Eggman keychains. The first is clear plastic, with raised lines for the borders and paint. It's made to resemble metal & enamel items. The pose is 'running away Eggman' from the early Sonic games. The second is more like a key tag, with clear acrylic & the art on a layer in the middle. It says "Dr. Eggman I like your style", with the Sega copyright beneath it. Both seem to be missing the actual chain/lead loop. (and as you can guess, if there's an Eggman one, then there's sure to be a Sonic & Tails one just like this, at least) The pose is fun & whimsical, and while not always practical (due to size) acrylic is sturdy & cool for keychains.
