The Format Print Folio Case is perfect for artists in need of a stylish and practical portfolio case, capable of storing photographs, sketches, matted prints, magazines, books, and more. Much like all of our products, the Print Folio Cases are designed to protect your work from the inside out (just check out our Preservation post). Featuring .100 thick acid free, lignin free, & PH neutral binder boards, as well as acrylic coated exterior paper. The interior folding flap has magnets to secure closure, thus reducing exposure to light, dust, and dirt. We also decided to keep the magnetic closure hidden to maintain a sleek and minimal design.
