The 4 inch tall Doctor Who Tardis Seatbelt Keychain w/ Belt Loop proudly displays Dr. Who's favorite home / vehicle, the TARDIS, on a fantastic double ring seatbelt keychain! Now that I think about it, is the TARDIS really a trailer? If that is the case, those guys on Gallifrey really know how to make things! The Doctor Who Tardis Seatbelt Keychain w/ Belt Loop is a durable keychain with plenty of room for keys. That sort of stuff is important if you're zipping around both time and space!
