10 x 7 3/4 x 1 Mailers

A 1 inch depth adds capacity for thicker documents, prints, and grouped materials that need rigid mailing protection. JAM Paper 10 x 7 3/4 x 1 inch photo mailers combine rigid paperboard with an expandable profile for artwork, certificates, photographs, presentation pieces, and client materials. The compact footprint keeps smaller contents organized while allowing additional thickness.

Unlike a conventional flat envelope, the dimensional construction accommodates multiple sheets or thicker paper-based pieces more comfortably. A sturdy white exterior supports professional presentation, and the peel & seal closure helps simplify packing. This design works well for office correspondence, photography shipments, creative work, and important printed materials.

Projects that need structure without a full shipping box can benefit from an expandable photo mailer. Portfolios, proofs, promotional sets, invitations, certificates, and small groups of documents can remain supported throughout transit. The added depth makes this size useful for specialized business and creative mailing requirements.
