Plastic ruler 20 cm INTERDRUK — 20 cm measuring scale, transparent
INTERDRUK 20 cm plastic ruler is a transparent measuring tool designed for precise metric measurements and drawing straight lines. The ruler is made of durable clear plastic with a 20 cm measuring scale marked along one edge. Its slim, lightweight construction makes it convenient for school, office, drafting, and home use, and it is compatible with pencils, pens and fine markers for accurate line work and small measurements.
The transparent material allows users to see the surface beneath for accurate alignment while the printed metric scale provides clear, easy-to-read markings. The compact 20 cm length balances portability with practical reach for most everyday measuring and drawing tasks. The smooth edges enable consistent strokes when using pencils or pens, and the durable plastic resists cracking under normal use conditions.
Place the ruler on the surface to be measured with the zero mark aligned to the starting point. Hold the ruler steady with one hand and read the metric markings to determine length. For drawing straight lines, position the pencil or pen against the ruler edge and move along the length with steady pressure. Use the transparent body to visually align the ruler with printed grids or reference points beneath the ruler.
Avoid exposure to high temperatures and sharp bending to maintain straightness and prevent deformation. Clean the ruler gently with a soft cloth and mild detergent if needed, and store flat to preserve accuracy.
