Duplo might be a simplistic twist on the ruler but its basic redesign gives it much greater functionality! A sliding component makes it easy to draw predetermined line lengths in a flash. Just slide it to the desired position and go! It also makes it quick and easy to identify and save the length of measured objects without having to peer closely or line up. Just snap it on and slide it closed for perfect measurements each time!
