Offering a superior writing surface and unsurpassed durability, M1 Dry Erase Board with a 28-gauge porcelain-on-steel surface is mounted to a 3/8" thick backing for added strength. Durable, porcelain-enameled surface keeps the dry-erase board from scratching or denting, even when installed in high-traffic schools and offices. Wear-resistant surface does not absorb ink, eliminating staining and ghosting that would otherwise result from repeated use. Easy-to-wipe board requires less cleaning, achieving a long-lasting, bright-white surface without the hassle. Board comes in sleek, satin aluminum frame with an accessory tray and protective endcaps. SmartPak tray minimizes clutter and keeps items within reach. Board includes one marker and one eraser.
