12 1/2 x 9 1/2 x 1 Envelopes

Important flat materials stay supported inside a firm mailer with a 1 inch capacity. JAM Paper 12 1/2 x 9 1/2 x 1 inch envelopes accommodate photographs, certificates, prints, artwork, presentations, marketing pieces, and document sets. This size works well for studios, offices, schools, print businesses, and professional mailing projects.

Sturdy photo mailer construction helps reduce creases and folded corners during handling. Multiple flat pieces can be grouped together while the firm exterior supports their shape in storage or transit. These protective mailing envelopes suit client proofs, event photographs, creative work, awards, and printed promotional materials.

Presentation-ready contents stay supported by substantial 130 lb construction. A clean white exterior leaves clear space for mailing labels, postage, recipient information, and company identification. Peel & seal closure allows efficient packing while helping materials remain securely enclosed.
