11 x 13 1/2 Mailers

Medium-to-large flat materials gain reliable support from JAM Paper 11 x 13 1/2 inch photo mailers. The rigid paperboard construction suits photographs, artwork, certificates, presentation pieces, brochures, and business documents that should remain flat during shipping. This versatile size offers useful capacity without the bulk of oversized parcel packaging.

Two neutral finishes allow mailings to take on either a crisp professional appearance or a classic kraft look. Peel & seal closures make packing simple, while the sturdy exterior reinforces contents through routine handling and storage. These envelopes fit photography orders, creative projects, client materials, and important printed correspondence.

When presentation and condition both matter, structured mailing supplies provide more support than flexible paper envelopes. Retailers, photographers, offices, and creative teams can use this size for prints, promotional materials, certificates, and other broad flat pieces. The generous proportions keep contents organized while maintaining a clean shipping profile.
