Chalk for Blackboards KOH-I-NOOR 6 pcs white (MPN 383020)

KOH-I-NOOR white school chalk, set of 6 pieces, is made for writing and drawing on traditional blackboards and chalkboards. Each stick delivers consistent coverage and produces clear, legible lines suitable for classroom lessons, presentations and informal sketches on slate surfaces. The chalk is formulated to leave minimal dust residues that can be removed with a standard duster or a damp cloth, and the compact packaging keeps pieces together for convenient storage and distribution.

Advantages

The chalk offers uniform hardness for steady writing without frequent breakage and provides good contrast on dark surfaces, making text and diagrams easy to read from a distance. Its composition reduces clumping and excessive dust, which simplifies board cleaning and lowers airborne particles in a classroom environment. The small, sealed pack is practical for organizing supplies and handing out to students.

Suitable for

• School classrooms and lecture halls

• Artistic sketches and quick drawings on slate surfaces
• Temporary markings on non-porous blackboard surfaces

How to use

Hold the chalk comfortably between fingers and apply light to moderate pressure to write or draw on a clean blackboard surface. For best results, ensure the board is dry and free from heavy residue; erase previous marks with a duster or cloth before writing. If the chalk tip becomes blunt, shape it by gently rubbing on the board edge or a clean surface. After use, store the sticks in their original pack to prevent breakage and keep them dry.

Usage recommendations

To minimize dust and extend the life of the chalk, write with steady strokes and avoid excessive pressure. Regularly clean the board with a damp cloth to prevent ghosting of previous marks and maintain high contrast. Keep the pack sealed and stored in a cool, dry place away from moisture.
