Just insert the pen and give it a quick spin!
The circle ruler can draw circles from 1mm to 110mm in diameter with a 1mm pitch (0.5mm pitch for diameters from 1mm to 9mm) faster, more accurately, and more easily than a compass. The inner circle rotates smoothly due to a bearing mechanism. The center position is equipped with a magnifying lens. The back side has an ink edge. ❶ The outer circle template can be used for diameters from 1mm to 20mm. ❷ The back side of the rotating circle prevents ink bleeding and smudging when drawing circles due to its floating structure. ❸ The high-precision rotating circle can be used for diameters from 20mm to 110mm. ❹ The small hole diameter on the rotating circle allows for the use of 0.5mm mechanical pencils or 0.1mm to 0.3mm sign pens. ❺ The large hole diameter on the rotating circle allows for the use of 0.5mm sign pens. ❻ The cross lines on the circle indicate the center of the circle. ❼ The center position is equipped with a magnifying lens. ❽ The surface acrylic plate (yellow) helps prevent eye strain and makes the lines easier to see. ❾ The outer circle functions as a 360° protractor. *For use with 0.5mm mechanical pencils only.
