Chinchilla keychain, originally purchased at an Asian import market. Extremely soft and very adorable. Size as shown next to ruler. This particular guy comes with a headphone jack connector to hang off your phone but he has a metal loop at the top of his head to accommodate a keychain, necklace, or whatever you choose. The photo showing the connector on the head is on one of the tan chinchillas. This chinchilla is yellow but has the same connector.
