## Long description

Corex 242820 drawing set includes a 20 cm straight ruler, two set squares and a protractor designed for measuring, technical drawing and school geometry tasks. The kit provides basic drafting tools for accurate line drawing, angle measurement and layout work in education, design and office use. All items are made from transparent material to allow clear visibility of drawing surfaces and markings.
Advantages
The set combines a 20 cm ruler, a 45° set square and a 30/60° set square together with a semicircular protractor in a single compact kit, reducing the need to buy tools separately. Transparent construction and printed graduations enable precise alignment and easy reading of millimetre and degree markings. The instruments are lightweight, stackable and suitable for storage in pencil cases or desk drawers.
Suitable for
School geometry and classroom exercises
Technical drawing and basic drafting
Office layout, sketching and measurements
Hobby and craft projects requiring straight lines and angle measurement
Key specifications
Straight ruler length: 20 cm
Set squares: one 45° and one 30°/60°
Protractor type: semicircular, degree markings 0–180°
Material: transparent rigid plastic
Graduation units: millimetres and centimetres
Finish: printed numerical and degree markings for visibility
How to use
Place the 20 cm ruler or the appropriate set square on the drawing surface and align it with reference points or grid lines. Use the printed millimetre graduations to measure linear distances and to draw straight lines with a pencil or technical pen. For angle measurement, position the protractor so its baseline coincides with the reference line, then read the desired degree mark. The set squares can be used to draw perpendicular and standard angle lines by aligning their edges with existing lines.
Usage recommendations
Store the kit flat in a pencil case or drawer to avoid bending. Clean the surfaces with a soft cloth to maintain visibility of markings. For higher precision tasks, ensure the working surface is stable and use a sharp drawing instrument aligned with the ruler edge.
