The simplest way to bind work into a portfolio book: the Pina Zangaro Adhesive Hinge Strip. To use, start by peeling back the release liner to expose the archival adhesive. Then adhere your artwork to the adhesive edge and place the sheet into your portfolio book or binder. An ideal system for screwpost portfolio books and 3-ring binders. Made of archival grade DuPont polyester, the Hinge Strips will not damage your work over time, are perfectly clear and will not tear. Available with standard hole configurations and packed in tens in a protective metallic, resealable bag.
