1. Excellent Visibility and Color Choice

This ruler stands out due to its transparent yellow color. This is not just an aesthetic detail – it offers several practical advantages:

KOH-I-NOOR is renowned for plastic products that are not brittle. This 30 cm drafting tool features optimal flexibility:

• Fracture Resistance: The plastic is designed to withstand daily use in a school bag or desk drawer.

Frequently Asked Questions (FAQ)

Is this ruler easily breakable?

While it is a hard plastic product, it possesses slight elasticity that protects against cracking during normal use, though it is not a "shatterproof" rubberized ruler.

Does the scale rub off over time?

KOH-I-NOOR uses high-quality printing technology, so the measurement scale is highly resistant to abrasion compared to cheap, unbranded alternatives.
