Eschenbach Pop Up Monocular

The Microlux 4x13 is a pop-up spring loaded monocular telescope. Squeezing with your hand will open the monocular and pressing on it closes it and protects the lenses on both ends. The rectangular shape prevents it from rolling off surfaces. This is an extremely handy little device that will sit in your pocket until you need it. Plus it looks like something Q may have invented.
