8CT JUMBO CHALK MARKERS (15MM TIP) | WINDOW MARKERS - VIVID COLORS

Eight oversized markers for high-impact signage.

Eight chalk markers with a 15mm jumbo tip — built for big, bold, can-be-seen-from-the-sidewalk signage. Vivid neon colors that pop on storefront windows, cafe sandwich boards, and large chalkboards.

Made for:

• Storefront window art and "open" signs
• Sandwich-board specials and sidewalk signage
• Large cafe and restaurant menu boards
• Trade show booths and pop-up event displays
• Sports bar specials, garage sale signs, and farmer's market signage
• Any chalkboard bigger than 24" x 36" — small-tip markers get lost on big boards

What makes them different:

• 15mm jumbo tip. Roughly 2.5x the width of our standard 6mm markers — built to be read from across a parking lot.
• Long-lasting, smudge-proof liquid ink. Non-toxic, low-odor, safe for indoor and outdoor use.
• Wipes clean with a damp cloth from non-porous surfaces — chalkboards, glass, metal, plastic, vinyl, and slate. Note: not for chalkboard paint or unsealed surfaces — always test first.
• Vivid neon palette for maximum visibility.
