Chalk for blackboards KOH-I-NOOR 6 colors, set of 6 pieces (model 147551)

KOH-I-NOOR colored chalk set contains six distinct colors in a compact pack of six sticks designed for use on traditional slate and blackboard surfaces. The chalk delivers clear, visible lines suitable for writing and drawing in educational, professional, and creative settings. Formulated for easy application and straightforward erasing from standard chalkboards, this set supports everyday classroom use as well as presentations and artistic projects.

Advantages

The chalk produces vivid, easily readable marks that contrast well with dark writing surfaces, improving visibility during lessons or demonstrations. Each stick is shaped for comfortable grip and controlled application, while the composition allows for reliable chalk-on-board performance and simple removal with a standard eraser or damp cloth. The compact six-piece format is convenient to store and transport, making the set practical for classrooms, meeting rooms, and workshops.

How to use

Hold the chalk between the fingers and apply gentle, even pressure to write or draw on a clean chalkboard surface. For best results, ensure the board is free of heavy dust before use; wipe with a dry eraser or a damp cloth and allow it to dry if necessary. Use different colors to emphasise headings, diagrams or separate content areas. Replace chalk pieces when they become too short for comfortable handling.

Usage recommendations

Store the chalk in a dry place and keep it in its original packaging or a small box to prevent breakage. To minimise dust dispersal, erase boards with a slightly damp cloth after dry erasing and ventilate the room. For detailed drawings, use lighter pressure; for bold lines, apply slightly firmer pressure. Avoid applying chalk on painted or delicate surfaces not intended for chalk use.
