Itoya ProFolio PolyZip Envelope - 11" x 17"

These envelopes are a great way to organize and store art and photography. They are made from durable polypropylene and are archival safe for long-term storage. An expanding gusset provides flexible storage for a single or a stack of art and photo materials, and the easy to use zip closure seals out the elements to help resist dust and moisture. They also have a single sheet pocket in the front for a routing slip or a content sample.
