Jumbo Chalk Markers are the perfect way to mark out your arena or convention centre floors, or other non porous surfaces. Concrete, plastics, other smooth decking, as well as pelicans, and road cases alike.
Once dry will withstand moderate foot traffic much longer than standard chalked rigging marking. Typically wipes off clean with mop, or damp rag, unless absorbed into porous surface.
Can also be as a bright marking on wood, drywall, concrete, glass, dry erase boards, etc. The markers are opaque, water-based, and pigmented.
