How to use

Place the ruler flat on the work surface and align its edge with the points you want to join or measure.

For measurement tasks, read from the zero point at one end and mark the required length. Store the ruler flat or in a pencil case to avoid warping.

Usage recommendations

Avoid prolonged exposure to moisture to maintain the straightness of the wooden edge. For precise cutting, use a fresh blade and steady pressure; for most classroom and office tasks the 0.5 mm thickness provides reliable guidance. Recycle according to local wood-recycling guidelines when the ruler reaches end of life.
