12 3/4 x 15 Mailers

Large documents and creative pieces require packaging that provides both space and reinforcement. JAM Paper 12 3/4 x 15 inch photo mailers are designed for photographs, artwork, brochures, certificates, catalogs, presentations, and other flat materials. Sturdy paperboard helps maintain shape during mailing while keeping the package professional and organized.

Crisp white and traditional kraft finishes both provide substantial support for important contents. Peel & seal closures allow quick preparation without additional adhesive, making them convenient for recurring business shipments. The larger surface area also accommodates mailing labels, identification, and company branding.

Creative professionals and business teams can use this size for pieces that should not be folded into standard envelopes. Portfolios, photographs, client materials, marketing collateral, and printed projects fit comfortably within the broad dimensions. The reinforced construction makes these mailing envelopes useful for both commercial distribution and personal shipments.
