They are \u003cstrong\u003enot recommended for porous surfaces\u003c\/strong\u003e such as raw wood, uncoated paper, or unsealed chalkboard paint — the ink will absorb and become difficult or impossible to remove.\u003c\/p\u003e\n\u003ch3\u003eQ: How do I erase the marks?\u003c\/h3\u003e\n\u003cp\u003eA: Simply wipe with a \u003cstrong\u003edamp cloth or wet paper towel\u003c\/strong\u003e. For stubborn marks or dried ink, use a slightly wet sponge with light pressure. On glass, a window cleaner spray works perfectly. No solvents or special erasers needed.\u003c\/p\u003e\n\u003ch3\u003eQ: Do the colors glow on LED boards?\u003c\/h3\u003e\n\u003cp\u003eA: Yes. The neon pigment formula is specifically optimized to fluoresce under LED backlighting, producing vivid, glowing color on illuminated chalkboards. Results are most dramatic in dim or dark environments.\u003c\/p\u003e\n\u003ch3\u003eQ: How do I activate the marker before first use?\u003c\/h3\u003e\n\u003cp\u003eA: Shake the marker well for 30 seconds, then press the tip down firmly on a scrap surface several times until ink flows to the tip. This primes the valve and ensures smooth, consistent ink delivery from the first stroke.\u003c\/p\u003e\n\u003ch3\u003eQ: Is the ink dusty or messy like traditional chalk?\u003c\/h3\u003e\n\u003cp\u003eA: No. The liquid chalk formula produces \u003cstrong\u003ezero dust\u003c\/strong\u003e. It is completely dust-free during use, making it safe and clean for food service counters, children’s classrooms, and any environment where chalk dust is a concern.\u003c\/p\u003e\n\u003ch3\u003eQ: What line widths can I achieve with the 15mm chisel tip?\u003c\/h3\u003e\n\u003cp\u003eA: The chisel tip gives you two line widths in one: use the \u003cstrong\u003ebroad flat face\u003c\/strong\u003e for wide strokes up to 15mm (ideal for bold lettering fills and backgrounds), or use the \u003cstrong\u003eangled edge\u003c\/strong\u003e for narrower, more controlled lines. It’s the versatility of a brush with the consistency of a marker.\u003c\/p\u003e","brand":"TTpen","offers":[{"title":"6 Color A","offer_id":55463184105777,"sku":"LCM15FC-1","price":21.0,"currency_code":"USD","in_stock":true},{"title":"6 Color B","offer_id":55463184138545,"sku":"LCM15FC-2","price":21.0,"currency_code":"USD","in_stock":true},{"title":"6 Color C","offer_id":55463184171313,"sku":"LCM15FC-3","price":21.0,"currency_code":"USD","in_stock":true},{"title":"12 Color","offer_id":55463184204081,"sku":"LCM15FC-4","price":21.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/2630\/3793\/files\/O1CN01kthsbz1NqvKmCDGvq__2884891622-0-cib.jpg?v=1785081771","url":"https:\/\/www.ttpen.com\/products\/15mm-wide-tip-liquid-chalk-markers-for-led-chalkboards-glass-menu-boards-window-signage","provider":"TTpen","version":"1.0","type":"link"}
