Anyone who has done electronics repair knows how irritating lost screws can be-if you"re lucky, you"ll end up with a slightly lighter laptop. If you"re unlucky, your $1,000 laptop will be brought to its knees by a $0.05 clip hiding under a table leg. Designed by fixers, for fixers, the 8"x10" Magnetic Project Mat solves this repair problem. Spacious and secure, the mat will catch screws as you pull them out of a device and hold them there. But fear not! The magnetic surface is safe for credit cards, hard drives, and other electronics.The included pen is uniquely suited for the Project Mat. It"s made by Staedtler, the German pen company that makes top-of-the-line artists" pens and pencils, as well as the expensive precision pens architects use for blueprints. Their Lumocolor Correctable pen doesn"t smear or wipe away like most dry erase markers. If you brush your hand across the mat while performing a repair, the ink doesn"t scratch or smear. But the eraser tip or a dry cloth erases the ink clean every time.
