Chalk Marker Securit BL-SMA100-V2-BL black 1–2 mm tip, pack of 2

The Securit BL-SMA100-V2-BL chalk marker in black is a twin-pack of liquid chalk pens with a 1–2 mm chisel tip. It is formulated to produce opaque, erasable chalk-like ink that adheres to non-porous surfaces such as chalkboards, glass, mirrors and windows. The marker is intended for temporary writing and drawing tasks where high contrast and legibility are required, for example on restaurant menus, retail signage and home message boards.

Advantages

These black chalk markers provide consistent, smear-resistant lines thanks to the chisel tip design and fluid ink flow. The ink dries to a bold, matte finish that is easy to wipe off with a damp cloth from suitable surfaces, while remaining visible and readable during use. Supplied as a pack of two, the set offers a backup marker for frequent use or simultaneous application in multiple locations.

Suitable for

• Writing and updating restaurant and cafe menus on chalkboards or glass
• Creating temporary window and mirror displays for retail promotions
• Labeling non-porous containers, trays and signage for events
• Home message boards, calendars and craft projects on glass or glazed surfaces

When it may not be suitable

This marker is not designed for use on porous surfaces like paper, untreated wood or unglazed ceramics; ink may bleed or be absorbed and become permanent. It is also not intended for long-term outdoor displays exposed to heavy rain or direct sunlight for extended periods, as weathering can reduce visibility and make removal more difficult.

Key specifications

• Tip type: chisel (1–2 mm line width)
• Ink colour: black (opaque liquid chalk ink)
• Suitable surfaces: non-porous surfaces such as chalkboards, glass, mirrors and windows
• Finish: matte, high-contrast when dry
• Pack size: 2 markers

How to use

Shake the marker well with the cap on before use to mix the ink. Press the tip several times on a scrap surface until ink flows, then write or draw using the broad or narrow edge of the chisel tip for different stroke widths. Allow the ink to dry for a few seconds to reach full opacity. To erase, wipe the marked surface with a damp cloth or sponge; for stubborn residues, use a non-abrasive cleaner compatible with the surface.

What to consider before purchase

• Confirm the marker is intended for non-porous surfaces; do not use on untreated or absorbent materials
• Test on a small area first to ensure compatibility and easy removal
• Consider the 1–2 mm chisel tip if you need fine detail or broader lettering
• Pack of two provides a spare but check storage conditions to avoid drying out

Usage recommendations

Store capped and upright in a cool place when not in use. For best results on glass and mirrors, clean the surface before writing. When creating menu boards, allow ink to dry fully between layers and avoid abrasive scrubbing when erasing to preserve surface finish.
