Writing chalk Faber-Castell 122540 — white sticks for blackboard and chalkboard

Faber-Castell 122540 writing chalk consists of white sticks formulated for clear marking on blackboards, chalkboards and other non-porous writing surfaces. The sticks produce visible, consistent lines suitable for classroom instruction, meetings, presentations and temporary markings. Designed for manual writing and drawing, the chalk erases cleanly from standard chalkboard surfaces when used with a dry or slightly damp cloth or eraser.

Advantages

The chalk delivers uniform pigmentation for legible text and drawings while producing minimal dust compared with lower-quality chalks. Each stick is shaped for comfortable handling and controlled strokes, allowing teachers and presenters to write steadily. The white color provides high contrast on dark surfaces, improving visibility from a distance.

Suitable for

• Classroom blackboards and teaching during lessons
• Meeting rooms and presentation boards
• Temporary markings on non-porous surfaces such as chalkboard paint or slate
• Art sketches and manual diagrams on chalkboard surfaces

Key specifications

• Color: white
• Format: stick-shaped chalk for manual use
• Surface compatibility: blackboards, chalkboards, slate and similar non-porous surfaces
• Mark visibility: high contrast on dark backgrounds
• Cleaning: erasable with a dry or damp cloth or felt eraser

How to use

Hold the chalk stick comfortably between your fingers and apply even pressure while writing or drawing on the chalkboard surface. For thin lines, use the tip of the stick; for broader strokes, apply a flatter edge. After use, remove marks with a felt eraser or wipe with a dry cloth; for more thorough cleaning, use a slightly damp cloth and allow the surface to dry before writing again.

Usage recommendations

Store chalk sticks in a dry place and keep them in their original packaging or a protective case to avoid breakage. Avoid excessive pressure that may cause the sticks to snap. If dust is a concern, erase with a damp cloth and ventilate the room during cleaning.
