How to use

Place the straight edge on the surface so the printed or drawn reference aligns with the ruler’s edge. Hold the ruler firmly with one hand to prevent slipping and draw along the straight edge with a pencil, pen or marker. For measuring, align the zero point of the scale with the starting point of the object and read the value at the other end. Store the ruler flat in a pencil case or drawer to keep the edge true and prevent warping.

Usage recommendations

Use a steady hand and light pressure when drawing to preserve the edge and avoid damage to delicate surfaces. Clean with a soft cloth and mild detergent if needed; avoid exposure to high heat or heavy loads that may deform the plastic.
