The 23 x 31 x 2" Art ProFolio ArtEnvelope Pro from Itoya is made from coated, weather-resistant polypropylene and stores and transports artwork, photographs, and Art ProFolio albums up to 22 x 30" in size. It has an expandable 2" gusset, which can accommodate thicker materials inside the textured interior envelope. The exterior of the envelope is reinforced with a strong perimeter stitching to withstand the weight of some materials. The fold-over flap, which has a pocket for a business card, closes the envelope and is carried with durable and comfortable nylon handles.
