## Long description

Keyroad Cyrkola combines an adjustable ruler, a protractor and a compass into a single compact instrument designed for schoolwork, drafting and basic geometry. The adjustable ruler slides to cover measurements from 15 to 30 cm, while the integrated protractor allows quick angle measurement and marking. A built-in compass function enables accurate circle drawing without the need for separate tools. A hanging loop provides convenient storage and easy access. The tool is supplied in mixed colors and is suitable for everyday classroom and home use.
Advantages
The multi-function design reduces the number of separate drawing tools required by combining measurement, angle layout and circle construction in one device. The adjustable ruler with clear graduations supports flexible measurement ranges without switching tools. The integrated protractor and compass mechanisms are positioned for straightforward alignment and stable operation. The hanging loop simplifies storage and helps keep workspaces organised, and the compact format is convenient to carry in school bags or pencil cases.

How to use
Slide the ruler section to set the desired measurement between 15 and 30 cm and lock it in position if the mechanism provides a fix. Use the ruler edges for straight lines and the protractor area to measure or mark angles directly on the work surface. For circles, position the compass point at the intended centre and rotate the compass arm to draw the circle at the required radius. Use the hanging loop to store the tool on a pegboard or hook when not in use.
Usage recommendations
For precise results, place the instrument on a flat, stable surface and ensure the sliding ruler section is fully engaged before measuring. Keep the protractor and compass areas clean and free of debris to maintain accurate markings. Store in a pencil case or hang by the loop to prevent bending or damage.
