Scaling a drawing by hand and still mixing up which groove is which? You're not alone. The Staedtler Mars Triang Divide 1 puts six scales on one 300mm ruler, each in its own colour-coded groove so your finger lands on the right one first try. Solid white plastic. No flex, no ghosting through the page. Grab it for the next art block and stop losing ten minutes to a fumbled scale
