Steel components, screws, miniature bearings and other ferrous parts can't roll away and disappear when you use this magnetic pad for repair and assembly/disassembly work. Perfect for use with machinery, miniature motors, model train engines and more. Pad can be cut to smaller sizes with scissors if required. Pad is approximately 12" x 12" x 1/32".

Note: The pad's low magnetic field is only on one side and will not harm or affect nearby electronics. But the pad should not be used for repairing cellphones, computers, digital cameras and other "smart" devices with memory cards.
