OptiMA® offers premium 28-gauge unframed magnetic dry erase and chalkboard panels, featuring porcelain steel surfaces on ½" particle board with Mylar backing. Available in white, black, and green, these panels are ideal for custom framing projects. Cut them to size using a 60-tooth carbide-tipped saw blade for precise results. Please note, these panels are designed for framing and are considered custom items; returns are not accepted. If you are looking for panels to adhere to your walls without trims, etc. you may want to look in our ""Full Height Walls"" section, at our ""Peel and Stick"" panels or at our ""Frameless White Painted Edge Boards"". Please note: All porcelain steel panels, cut or whole are considered a custom item. They cannot be returned. Thank you!
