MIDORI ALUMINUM RULER
Draw, cut, and measure clean lines with this non-slip ruler! It features an aluminum body with a non-slip strip down the center of the back. The non-slip material prevents the ruler from moving as you use it, keeping your lines neat. Simply press the center of the ruler as you work to hold it in place. To move the ruler, press down on the ridged edge to lift the non-slip strip away from the work surface. A handy magnet in the back of the ruler lets you attach it to a metal shelf, desk, or locker for quick access.
