Big Tab Write-On Dividers are perfect dividers for all your classification folders. Simply use a ballpoint pen or pencil to easily label your tabs. You can write and erase on the five laminated tab surfaces to reuse the dividers. Side tabs are 50 percent bigger than typical tabs for even more available writing space. The top is pre-punched with two holes. Single-side, copper-reinforced holes provide extra tear-resistance against the sharp metal prongs of classification folders.
