Light, extremely accurate and has (a very cool), non warping bamboo core. Check your ruler’s accuracy: make tick marks at each 1” mark. Swing your ruler around, line up the 12” mark with the 1” mark, 11” with the 2”…. Look closely, they should line up exactly! If they don’t, the ruler is not accurate & is useless for accurate measuring! Here’s one that is!
