Description Write on, erase and reuse these 1-1/4\" laminated tab indexes. The Mylar matte finish lets you write a title on the tabs and erase it so you can reuse these indexes again and again. Use a pen or pencil to write on the tabs. 100 lb. basis weight sheets are three-hole punched with 9/32\" holes and have a reinforced at binding edge. Dividers are made of 80 lb. stock with a high percentage of recycled material.
