Dry-erase markers are designed to write on whiteboards, glass and other nonporous surfaces. The durable, polyester chisel tip lets you write in broad, medium or thin lines. Low-odor, quick-drying ink erases easily with a dry cloth or eraser with no ghosting or shadowing once the writing has been erased. Cap color matches ink color. The eight-color set includes one of each: black, blue, red, green, yellow, orange, brown and purple. Ink is certified AP nontoxic.
