MagPad Magnetic Tool Holder

You can of course use the Mag-Pad on any kind of surface if you're just keeping your tools flat and want to prevent your tools from rolling away, but you can also attach it to the side of a car, on a wall, pillar, or even on the under-side of a car hood to keep your tools stuck to it while keeping them in a perfect location for quick usage

The Mag-Pad is a flexible, anti-scratch, ridiculously strong magnetic pad.  Measuring just 1/4" thick, it takes up almost no room and can hold just about anything you throw at it.  The Mag-Pad is a great addition to any mechanics toolbox.
