Guaranteed to remain as clean as the first day you use it!Unlike conventional dry-erase boards which have a porous paint layer with tiny valleys which trap ink, Total Erase technology adds a smooth, non-porous layer that keeps marker ink on the surface. The surface then wipes clean each and every time you use it, keeping the board looking like new even after years of use. Designed to enhance any prominent workplace, each board features a radius edged frame for a modern feel. There is no need for cleaners, and boards are guaranteed never to stain or ghost. Boards will look great for years because of a hard durable surface that is scratch and dent resistant. Easy to draw straight lines with subtle grid pattern viewable only from close distances. Available in 3 sizes with oak or aluminum frame finish.Overall dimensions: ALUMINUM FRAME: TEA405: 48H x 60"W TEA485: 48H x 72"W TEA408: 48H x 96"W OAK FRAME: TEW405: 48H x 60"W TEW485: 48H x 72"W TEW408: 48H x 96"W
