How to use

To use the ruler, place the zero mark at the starting point of the distance you wish to measure or the line you intend to draw. Hold the ruler firmly against the paper to prevent slipping, and use a pencil or pen to mark the desired length or trace along the straight edge. Ensure the ruler is laid flat on a stable surface for the most accurate results.

What to consider before purchase

• Verify that the 20 cm length meets your specific measurement requirements.
• Consider if a transparent material is preferred for your specific drafting needs.
• Ensure the ruler fits within your intended storage space, such as a pencil case or desk drawer.

Usage recommendations

For best results, clean the ruler periodically with a soft, dry cloth to maintain its transparency and ensure that markings remain easy to read over time. Avoid using sharp blades directly against the plastic edge to prevent nicks and uneven surfaces.
