Looking for the superior clarity of polyester in a sheet that will lie flat in a screwpost book? Look no further than the Pina Zangaro 14x11 Flex-Hinge Polyester Sheet Protectors. These top-and-bottom loading 100% archival sheets are much clearer than polypropylene sheets and they lie perfectly flat thanks to a hinged binding edge. Made of inert, unplasticized, heat resistant and chemically stable archival quality, heavy-duty DuPont polyester. Sold in packs of 10 in a protective metallic resealable bag
