Key specifications

• Length: 30 cm measuring range
• Material: durable transparent plastic
• Graduations: clear metric (centimetre and millimetre) markings

How to use

Place the ruler with its zero mark aligned to the start point of the measurement or drawing. Hold the ruler firmly with one hand to prevent slipping and use a pencil, pen or cutting tool along the straight edge to mark, draw or cut as needed. For measurements, read the value at the point indicated and for precise lines ensure the surface is flat and the ruler is pressed evenly against the material.

Usage recommendations

Store the ruler flat or in a pencil case to avoid warping; avoid exposure to high heat or heavy loads. Clean with a soft cloth to maintain clear graduations. For cutting tasks, use a cutting mat beneath the material to protect both the ruler edge and the work surface.
