Chalk Marker PENTEL SMW56 Jumbo, yellow — refillable liquid chalk marker, broad tip

PENTEL SMW56 Jumbo in yellow is a refillable liquid chalk marker designed for writing on non-porous surfaces such as chalkboards, glass, mirrors and windows. The marker delivers thick, opaque, chalk-like strokes with a broad tip that produces bold visible lines suitable for signage, menu boards, classroom displays and craft projects. The ink is formulated to be erasable from smooth surfaces with a damp cloth or suitable cleaner, while providing clear, consistent coverage for repeated use.

Advantages

The broad tip of the PENTEL SMW56 Jumbo creates uniform, high-visibility lines that reduce the need for multiple passes. Its refillable ink system minimizes waste and allows extended use when refills or compatible cartridges are available. The yellow pigment provides strong contrast on dark backgrounds and good visibility on glass and mirrors. The liquid chalk formulation is designed to be removable from non-porous surfaces without aggressive abrasion when cleaned correctly.

How to use

Before first use, shake the marker with the cap on to mix the ink uniformly. Prime the tip by pressing it down on scrap paper or a test surface until the ink flows and the tip is saturated. Write on clean, dry non-porous surfaces such as glass, mirrors or chalkboards for best results. To erase, wipe with a damp cloth or a suitable non-abrasive cleaner; for stubborn marks, allow a damp cloth to sit briefly on the mark before wiping. Replace the cap after use to prevent drying.

Usage recommendations

Store the PENTEL SMW56 Jumbo horizontally when possible to maintain even ink distribution. Test the marker on an inconspicuous area before application on delicate or unfamiliar surfaces. For long-lasting performance, use compatible refills and avoid porous surfaces where the ink may soak in and become difficult to remove.
