This is, of all things, a nail clipper. It can be used on a human finger or toenail. It's goldtone metal with a metal & enamel Tails icon on the leverage/ push down part. It looks like he was drawn sitting on something, but that the item is left out of the graphic. It's a seldom-seen classic art of him, very interesting & rare. The back is marked "Tails Sega" with the copyright. If there's a Tails one, you know there's got to be a Sonic one too. Value may be at about $50 due to rarity.
