This 10-pack of 8.5 x 11" Refill Sheet Protectors from Prat are refillable pages designed to hold photographs, artwork, and inkjet-printed materials in a portfolio for display in a vertical orientation.
The archival, clear polypropylene pages are compatible with the Volga 121, Modebook 149, and the Pampa 143, 148, and 163 spiral books. Inside each page there is an acid-free paper insert, which will not degrade your stored materials over time. In addition, inkjet, laser, or copy toner will not transfer to the pages. The pages passed the Photographic Activity Test (PAT), which makes them archival.
