Is this ruler flexible?
This ruler is rigid, designed for precise drawing. It is not a "flexible plastic" type, so it maintains its straight shape better during measurements.
Does the scale rub off over time?
KOH-I-NOOR uses high-quality printing technology, so the scale remains bright even after long-term use, provided the ruler is protected from severe mechanical damage.
