17 x 21 Mailers

Oversized creative work needs sufficient surface area to remain flat and properly supported during mailing. JAM Paper 17 x 21 inch photo mailers accommodate photographs, posters, illustrations, reports, artwork, presentation boards, and other oversized paper-based materials. Their rigid construction provides a stronger enclosure than flexible document envelopes for valuable flat pieces.

Color choice allows professional shipments to take on either a crisp or natural kraft appearance. White and brown kraft options combine sturdy 130lb construction with peel & seal closures for straightforward preparation. The oversized dimensions make these mailing envelopes especially useful for materials that would otherwise need to be folded.

Artists, photographers, studios, agencies, and offices often send work that should arrive flat and presentable. These jumbo photo mailers provide space for portfolios, large prints, promotional pieces, client projects, and important visual materials. Their broad profile supports professional presentation while reducing the need for makeshift cardboard reinforcement.
