Measuring 2 inches across, the TMNT Leonardo Head Keyholder Keychain is a super cool soft, yet rigid means to spruce up one of your keys! I bet you have a bunch of keys and you just fumble through them all of the time, trying to remember which one is which. Well, I bet the TMNT Leonardo Head Keyholder Keychain would certainly help that out now wouldn't it? I would certainly let the Teenage Mutant Ninja Turtles look after my house key that's for sure.
