Learning Resources Safe-T Compass
This durable, 6″ flat compass can draw circles from 1/4″ to 10″ in diameter. Unique design eliminates the sharp point found on traditional compasses. It can be used with assorted writing instruments. Use the internal circle templates on one end. Two built-in, mini rulers offer measurements in 1/16″ along one edge and millimeters on the other. You can also insert your writing utensil in one of the pre-punched holes along the ruler to make a certain size circle.
Compass is made with shatter-resistant SAFE-T plastic.
