A 360° open design protractor can accurately measure angles without having to physically move the protractor, causing potential issues and inaccuracies in measurement. The open design makes it easier to see the lines and angles being drawn or measured behind the protractor. The opposing 2-line gradations allow students to see that angles are measured the same way whether they’re positioned clockwise or counterclockwise. 

The bevelled edge strengthens the protractor’s durability by reducing the effects of normal wear and tear, whilst the clear plastic construction eliminates the risk of breakage and improves visibility at the same time.
