Perfect Circle / Compass

Perfect Circle
Perfect Circle

As opposed to using a compass, problems, including easily tilting lines and puncturing the paper for anchoring the compass, have been solved.

First, move the adjusting rod on the side of your [Perfect Circle] to the desired radius for the circle. Align the central axis on the desired position for the center of the circle, and then press the button for the central axis to sink into the body while the silica gel sucker adheres to the paper. Move the adjusting rod, and draw the perfect circle.
