## Long description

KOH-I-NOOR Ekierka 16 cm with angle measure is a compact multifunctional drawing tool combining a 16 cm straight rule and an integrated protractor. The transparent design allows clear visibility of drawing surfaces while the graduated edge supports basic length measurements.

Advantages
The ruler set integrates a straight edge and a protractor into a single lightweight instrument, reducing the need to switch between tools.

Material: transparent plastic for visibility

How to use
Place the transparent ruler on the drawing surface with the straight edge aligned to the reference line. Read and mark lengths using the graduated edge. For angle measurement, align the protractor center point with the vertex, rotate the ruler or mark the required degree on the protractor scale, and draw the angle line using the straight edge. Use steady pressure to avoid slipping and ensure the tool lies flat for accurate readings.
Usage recommendations
Store the ruler flat in a pencil case or stationery drawer to protect the graduations and protractor scale. Clean gently with a soft cloth to remove pencil or ink marks; avoid abrasive cleaners. For precise technical work, confirm measurements against a calibrated instrument if higher accuracy is required.
