## Long description

Tetis 20 cm plastic ruler is a lightweight, straight measuring tool intended for precise linear measurements, drawing and routine school or office tasks. The transparent plastic construction provides clear visibility of the underlying surface and printed scales, while the straight edges guide pencils and pens for accurate lines. Its compact 20 cm length makes it easy to carry in pencil cases and suitable for classroom desks, home study and hobby projects.
Advantages
This Tetis ruler combines a rigid straight edge with a clear plastic body that resists everyday wear and allows easy alignment of markings. The 20 cm size balances portability and working length, enabling measurement of most standard tasks without being bulky. The smooth edges offer stable guidance for drawing and drafting, and the lightweight design reduces pressure on paper when tracing lines.

Key specifications
Length: 20 cm
Material: transparent plastic
Shape: straight edge
Weight: lightweight, pocket-friendly
Primary use: linear measuring and drawing guidance
How to use
Place the ruler on the work surface aligning one edge with the desired start point. Hold the ruler firmly to prevent shifting and draw along the straight edge with a pencil or pen for a precise line. For measurements, align the zero mark with the starting point and read the value at the end point. Clean the ruler with a soft cloth to remove graphite or ink; avoid abrasive cleaners to preserve clarity and markings.
Usage recommendations
Store the ruler flat in a pencil case or desk drawer to prevent warping. For best accuracy, use on a flat, stable surface and apply even, light pressure when drawing. Replace the ruler if the edge becomes chipped or bent, as deformations can affect measurement precision and drawing straightness.
