Quickly and easily put together a bound presentation using this three-piece DIY kit. No binding machine required! Kit includes two black 5/16" ProClick® binding spines, two sets of pre-punched covers, 50 sheets of prepunched 11" x 8.5" paper and a zip tool. Simply print out your presentation materials on the pre-punched paper and snap on the covers and spines. ProClick® spines allow easy editing without a machine or tool -- spines snap open and close by hand, allowing you to add or remove pages on the fly. Included covers feature clear fronts and black backs. Kit's included materials combine to create two 25-page bound documents.
