New, all-in-one instrument used to measure and trace geometric figures. Replaces a math compass, ruler, protractor and set square. No sharp edges means no injuries. Features a central rule for simpler, faster, neater and more precise tracing, the pencil never leaving the sheet. Trace circles with a 10-110 mm radius, precise to the millimetre. Use with a hard lead pencil (3H or 2H) or a fine point marker. Sturdy plastic. 14.5 x 6 cm.
