Yato YT-69930 writing chalk 12 pc(s)

Yato YT-69930 writing chalk set includes 12 sticks designed for marking and writing on a wide range of surfaces. Each pack contains a mix of colours — white, red, green, navy blue, yellow and black — with two sticks of each shade. The chalk sticks measure approximately 120 x 12 mm and are formulated to leave clear, visible marks on metal, wood, stone, concrete and similar materials.

Advantages

The set offers durable, high-contrast marks that remain visible on rough and smooth surfaces. Colour variety makes it easier to code, highlight or differentiate marks at a glance. The thick, 120 x 12 mm sticks are comfortable to hold and suitable for manual marking in workshop, construction and craft environments. The formulation is appropriate for temporary and semi-permanent lines, and the sticks break-resistant enough for everyday use.

Suitable for

• Marking metal parts and sheet metal for cutting or welding
• Layout and measurement marking on wood and carpentry work
• Indicating points and lines on stone, concrete and masonry
• Colour coding of materials and on-site annotations

How to use

Select the appropriate colour for the task and hold the stick at a comfortable angle to the surface. Apply steady pressure to produce clear lines; increase pressure for deeper or more visible marks on rough or porous materials. For more precise lines on metal or wood, use a straightedge or guide. After use, store the sticks in their original packaging or a dry container to prevent damage and contamination.

Usage recommendations

Use on clean, dry surfaces for best visibility. Test on an inconspicuous area if permanence is a concern. For removal on non-porous surfaces, wipe with a damp cloth or appropriate solvent; removal from porous materials may require light sanding or scraping.
