The Pina Zangaro Polyester Sheet Protectors are high quality folded protectors that feature a strong black liner page. They are manufactured to the highest industry standards. They feature multi-rings for portfolio use as well as 3-ring binders.
Note: Polyester sheets have hole-spacing which allows them to fit into screwpost books, but this is not recommended since the pages would not lay flat.
