Liquid Chalk Pens
Clean, vivid POS that sells
Liquid chalk pens (a.k.a. liquid chalk markers) turn any non-porous chalkboard into a crisp, dust-free point-of-sale display you can update in seconds. They lay down bold, high-contrast colour, dry quickly, and wipe clean—perfect for promos, menus, and event messaging you change often. Carmel Industriesuni-ball
Why they’re convenient
-
No mess, high impact. Water-based ink gives sharp lines without chalk dust and removes with a damp cloth (use a little mild detergent or a purpose cleaner for stubborn marks). Carmel Industriesuni-ballDeflecto
-
Indoor/outdoor options. Many professional markers are smudge-resistant when dry and even rain-resistant—handy for doors and pavement-facing boards. uni-ballwulffsupplies.com
-
Fast to deploy. Shake, prime the nib (press until ink flows), write, let dry for a couple of minutes—done. VKF Renzel GmbH
Use on the right surface (important)
Liquid chalk works best on non-porous surfaces: sealed chalkboards, glass, metal, acrylic, and laminated boards. Avoid raw slate or unsealed chalkboard paint (it can stain); when in doubt, test a small corner first. Carmel Industriesuni-ball
How to apply for clean, legible results
-
Prep the board: wipe clean and dry.
-
Prime the pen: shake, press the nib on scrap until ink saturates. VKF Renzel GmbH
-
Block your layout: headline → key item/offer → clear price/CTA.
-
Write big to small: use a chisel tip for headlines, bullet tip for details.
-
Let it cure: give a couple of minutes to dry; add highlights/shadows after. VKF Renzel GmbH
-
Refresh quickly: remove with a damp cloth; for ghosting, use a chalkboard cleaner per the marker brand’s guidance. Deflecto
Turning chalk pens into a POS powerhouse
-
One more sign = more sales. On-premise signage research found one additional sign correlated with an average 4.75% increase in annual sales—your chalkboard is the easiest “extra sign” to add near the decision point. The Signage Foundation
-
Write for speed: 3–5 word headline, one benefit, one price. Keep copy scannable from 2–3 metres.
-
Colour with purpose: use white for body copy, one accent colour for the offer/price so the eye knows where to land.
-
Daypart your messages: swap lunch → evening in seconds; keep a handful of “evergreen” offers ready to rewrite.
-
Upsell naturally: feature high-margin adds (sides, desserts, bundles) at counters and tables.
-
Wayfinding wins: arrows and mini prompts (“Order here”, “Pay at bar”) reduce friction and move queues.
Care & maintenance
-
Cap after use; store horizontally to protect the tip.
-
Avoid long dwell time on porous/matte boards to prevent staining.
-
For semi-permanent displays, choose rain-resistant formulas and/or seal over the artwork if you don’t want it wiped off. wulffsupplies.comYouTube
