Dry-erase markers' patented three-chamber design delivers continuous ink flow for bolder color and more consistent line quality. Use on dry-erase boards, ceramic, glass and other nonporous surfaces. Low-odor, quick drying ink erases easily. Markers offer a see-through ink level gauge and unique antiroll cap. Marker kit includes one each of red, blue, green and black AP certified chisel point markers, cleaning eraser, and two-ounce pump spray cleaning solution for dry-erase boards.
