Chalk Marker PICA MARKER 591-44 — yellow, refillable chalk sticks, pack of 12

PICA MARKER 591-44 yellow chalk sticks are refill elements for chalk-style markers, supplied as a pack of 12. These refill sticks provide an opaque yellow pigment formulated for clear, visible markings on non-porous surfaces such as glass, whiteboards, chalkboards and laminated signs. Designed for quick replacement, the refill sticks restore marker performance and maintain consistent line quality for signage, temporary labelling and creative applications.

Advantages

The refill sticks are refillable and compatible with PICA chalk-style markers, enabling continued use of the original marker body without needing full replacement. The opaque yellow pigment produces high-visibility lines and good coverage on dark and light non-porous surfaces. Supplied in a pack of 12, the set reduces the frequency of single-item purchases and is suitable for environments where frequent marker renewal is required. The design supports straightforward tip exchange and reliable, consistent writing performance.

Suitable for

• Writing and drawing on glass windows and storefront signage
• Temporary labels on laminated surfaces and plastic containers
• Whiteboard and chalkboard marking in shops, cafes and classrooms
• Creative projects, displays and event signage

How to use

Allow the marker body to be empty or remove the worn refill according to the marker manufacturer's instructions. Insert a PICA MARKER 591-44 refill stick firmly into the marker housing until it seats correctly. Test the marker on a non-critical surface and stroke until pigment flow is normal. If necessary, prime the tip by pressing gently on a disposable surface or rotating the tip to achieve desired line thickness. Use only on recommended non-porous surfaces and follow surface cleaning guidance to ensure optimal adhesion and removal.

Usage recommendations

Store refill sticks capped and upright in a cool, dry place away from direct sunlight. For long-lasting visibility on frequently cleaned surfaces, allow markings to dry briefly before wiping. When changing refills, handle tips carefully to avoid contaminating the pigment and to maintain clean, even lines.
