Ruler plastic 20 cm Pratel — Pratel ML104-00

Pratel plastic ruler 20 cm ML104-00 is a compact measuring tool designed for precise metric measurements up to 20 cm. The ruler features clear graduated markings on a lightweight, rigid plastic body that resists bending during everyday tasks. Its portable size makes it easy to carry in pencil cases, school bags or desk drawers and supports drawing, drafting and basic craft measurements.

Advantages

The ruler combines clear, easy-to-read metric graduations with a slim, lightweight profile that maintains stiffness for accurate lines. Its transparent or translucent plastic surface (depending on production batch) allows for improved visibility of the workpiece underneath. The straight edges provide reliable guidance for drawing and cutting, and the compact 20 cm length balances usability and portability for students and office users.

Suitable for

• Schoolwork and classroom exercises requiring metric measurements
• Office tasks such as quick measurements, drawing straight lines and document layout
• Basic drafting and technical sketches at small scale
• Hobby and craft projects that need short, accurate measurements

Key specifications

• Length: 20 cm measuring range
• Scale: Metric graduations (millimetres and centimetres)
• Material: Rigid lightweight plastic
• Edge: Straight guide edge suitable for drawing and cutting
• Design: Compact, portable size that fits pencil cases and desk drawers

How to use

Place the ruler on the surface aligned with the desired start point; ensure the zero mark is positioned correctly before taking a measurement. For drawing straight lines, hold the ruler firmly with one hand to prevent shifting and run your pen, pencil or cutter along the straight edge. When measuring small objects, read the nearest millimetre marking at eye level to reduce parallax error. Store the ruler flat to prevent warping.

Usage recommendations

For the most accurate results, use on a flat, stable surface and avoid excessive bending or heavy pressure. Clean gently with a soft cloth to maintain visibility of markings; avoid solvents that can damage plastic. Replace the ruler if graduations become worn or edges become nicked to ensure continued measurement precision.
