A reliable measuring tool is essential in every office, school, or creative workshop.

We have tested this product and find it to be a highly practical tool for daily use.

Technical Summary (Specifications)

1. Natural Material and Sustainability

This measuring tool is made from high-quality, well-sanded natural wood. This provides several advantages:

• Grip: Unlike plastic rulers, the wooden version slips less on paper surfaces, making it easier to draw straight lines.
• Eco-friendly: A more sustainable choice for environmentally conscious consumers.
• Temperature Resistance: Wood does not deform due to ambient temperature changes, maintaining its shape over time.

2. Measurement Precision and Visibility

The 30 cm length is optimal as it perfectly fits standard A4 paper (where the long edge is 29.7 cm). The black gradation on the light wood base creates high contrast, making numbers and markings easy to read even in low light conditions.

3. Drawing Performance

The Centrum drawing tool features smooth edges that allow for precise lines with minimal effort. Since wood has a slight elasticity, this ruler is more resistant to breaking than cheap plastic alternatives, which often shatter under slight pressure.

Verdict

The CENTRUM 30 cm wooden ruler is a time-tested choice. It is ideal for pupils, students, engineers, and anyone who appreciates natural materials and reliability. It is an economical and ecological solution that ensures precise results for any measuring or drawing task.

Frequently Asked Questions (FAQ)

Is the surface of the ruler smooth and splinter-free?

Yes, CENTRUM products are carefully sanded, ensuring the surface is safe for students to use without the risk of splinters.

Is this ruler suitable for use with wet ink?

Wood naturally absorbs moisture, so when using liquid ink, it is recommended to wipe the ruler clean to prevent ink from soaking into the edges and smudging subsequent drawings.
