Geometry triangle / set square for drawing circles, shatterproof, 16 cm

Product description How it works: for drawing, two pens are inserted into the recesses at the distance of the desired radius. A pen is then held in place as the centre as the second pen is slowly pulled around the solid pen. Thanks to the possibility to hold the pen either with the right or left hand, both right-handed and left-handed users can work optimally with it. Other sizes / designs are already in development and will follow promptly Place two pencils in the cavities at a distance from the desired radius. Hold one pen firmly in place as the centre point and then slowly pull the second pen around the fixed pen to draw a circle.
