Covert - Magnetic Security Drawer Latch

The cool new Quirky Covert is a clever magnetic security latch that keeps drawers secured from young children or anyone who doesn't understand the principles of magnetism. Just install on a drawer or cabinet door and swipe the included magnetic key on the outside to lock or unlock the inner sliding latch. A very simple and non-obvious solution to drawer security

It's still in the development phase over at Quirky.com, but I can definitely see this inventive idea going into production soon enough.
