When you want nothing between your work and the viewer, use a mounting sheet rather than a sheet protector. This technique is expecially useful for fold-outs and brochures. A variety of mounting adhesives are available to adhere your work to the mounting sheets. The hinged design allows these sheets to lie flat when used in a screwpost book. Made of 10 pt. black acid-free and lignin-free paper, approved by the Library of Congress for archival storage, pass the Photographic Activity Test (PAT) and meet all ANSI requirements for archival storage. __________________________________________________________ * * PLEASE NOTE: The collection of BLACK FLEX-HINGE SHEETS has been DISCONTINUED--some sizes will remain for sale as long as there is stock.
