The OEM Quartet EnduraGlide dry-erase marker set includes four markers designed for use on dry-erase boards, ceramic, glass, and other nonporous surfaces. Featuring patented three-chamber technology, these markers deliver bold, continuous color with a steady flow for smooth writing and clean erasing. The convenient see-through barrel allows you to monitor ink levels, while the roll-resistant cap prevents markers from rolling away. With low-odor, nontoxic, quick-drying ink, these markers are ideal for both home and office use.
