Low-odor, nontoxic dry-erase markers work well on whiteboards, glass and other nonporous surfaces. Marks wipe off easily with a dry cloth or eraser. Durable chisel tip writes in three line widths and won't "mush" or fray. Eight-color set includes black, blue, red, green, purple, yellow, orange and brown. Markers are ACMI certified to meet Federal Standards of nontoxicity and conform to ASTM D-4236 so they are safe for office, school or home.
