Sturdy and practical with excellent write-on/wipe-off qualities, Ghent's M2 Non-Magnetic Whiteboards provide years of reliable performance at an affordable price point. To ensure long-lasting durability, non-magnetic M2 board surfaces are applied to a quarter-inch thick hardboard backing, which is then enclosed within a satin-finished, anodized aluminum frame. For added convenience, M2 boards also include a detachable Smart-Pak board-accessories tray with protective end caps. Large-format M2 board surfaces are shipped in two piecessimply use the included joiner strip, which gives the illusion of one seamless board surface, before mounting. Both pieces are shipped in the same carton. Backed by Ghent's full 10-year performance guarantee.
