A small, lightweight solid brass telescope keychain with real optics inside! Makes a great gift. The inner barrels slide out for increased magnification. Length varies from 48mm to 67mm (1.9-2.6") between the closed and open positions. The manufacturer claims that this provides a magnification of 2X, although I think it's less than that. Nevertheless, this is a pretty cool item.

A neat item to put keys on, especially ones used for astronomy. Like the fact that it telescopes out and you can see through it. It is magnified as well, unknow magnification.
