Here's what the "figure & strap" Sonic Adventure 1 keychains looked like when they were in the packaging. Each keychain has a fully 3D figure of the character & a nylon black strap with their name. Each SA1 character was made this way as a sold-separatly keychain. The package has some STK character art on it & some text on the back. The keychain & figure are kept safe by the plastic bubble that's just snapped onto the card-backing. (so its not impossible to open).
