Microscope on a keychain unlocks the secrets of the very small, and of your house, car, tool box, or sample kit. Whatever you have locked with the keys on the key chain! The microscope is actually a plastic magnifier, 5/8" dia x 1-1/2" long OA and is of surprisingly good quality!! The packaging says it is 20X but we estimate it is in the 10X to 20X range. The key chain snaps on with a 2" long chain and has a circle holder for keys. It could double as a belt clip for the magnifier. Durable, great for kids, camping and general knock about service.
