8 1/2 x 13" #3 Jiffy Rigi Bag® Mailers

The #3 Jiffy Rigi Bag® Mailer is a rigid, self-sealing mailer built from kraft laminated fiberboard that prevents contents from bending, shifting, or creasing in transit — no supplemental stiffeners required. The cohesive self-seal flap folds over to close securely without tape or moisture activation, and a built-in tear strip gives recipients clean, tool-free access.

These mailers are well-suited for e-commerce fulfillment, retail distribution, direct mail campaigns, and photo or print shipments where surface and edge integrity are critical. The rigid panel construction makes them a reliable choice for legal-size documents, certificates, unframed artwork, and flat media that cannot tolerate flex or corner damage during handling.

Sold in cases of 200, the fiberboard panel reinforces corners and edges against compression stress common in parcel handling environments. The 8-1/2 x 13" interior accommodates standard legal documents and comparably sized flat products, and the case quantity supports consistent bulk stocking for high-volume shipping operations.
