Wooden ruler Cresco Kosmonauta — 30 cm measuring scale, straightedge for drawing and school use

Cresco Kosmonauta wooden ruler is a 30 cm straightedge made for measuring, drawing and everyday school use. It features a printed metric scale along one edge on a rigid wooden body that provides a flat, stable surface for accurate lines, sketches and geometry tasks. The simple construction and moderate weight make it easy to position on paper and durable enough for repeated classroom or workshop use.

Advantages

The wooden construction offers a stable, non-flexing edge for drawing and measuring. A clearly printed metric scale ensures quick reading of centimetre and millimetre marks. The 30 cm length covers common measurement needs for schoolwork, technical sketches and hobby projects while remaining compact for storage in pencil cases or tool kits. Its straightedge profile helps produce clean lines with pencils, pens or ink without slipping when pressed lightly.

How to use

Place the Cresco Kosmonauta wooden ruler on the surface aligned with the points you want to measure or connect. Hold the ruler firmly with one hand to prevent movement and draw along the edge with the other hand using a pencil, pen or technical pen. For measurements, read the metric markings from the zero point and note centimetre or millimetre increments. Store the ruler flat or in a pencil case to avoid warping and keep the printed scale legible.

Usage recommendations

To maintain accuracy, avoid prolonged exposure to moisture and excessive heat which can warp wood. Clean the surface with a dry or slightly damp cloth; avoid abrasive cleaners that may remove printed markings. For precise technical work, use the ruler on a stable, flat table and keep the edge free of dents or heavy wear.
