Business Source Ring Binder Index Divider Strong, insertable tab indexes resist tearing because of the plastic reinforcement made of clear Mylar on the binding edge. Buff index material provides needed body to turn the contents. Three-hole punched design inserts fit easily into standard-size binders. Included index inserts for the subject tabs come on a strip and are scored for easy separation. Ring binder indexes are made of 28 lb. stock.
