Stayflats Plus® Mailers in 9 3/4 x 12 1/4 inches are self-contained rigid mailers constructed from .028 kraft chipboard, delivering built-in stiffness without requiring separate backing boards or inserts. The kraft material keeps individual piece weight low, which helps control postage and carrier costs on high-volume flat-item shipments.

These mailers are well-suited for e-commerce sellers, print studios, photographers, and legal or administrative offices shipping documents, certificates, photos, artwork, and similarly sized semi-rigid goods that cannot arrive bent or creased. 

Each mailer features a peel-and-seal self-adhesive flap for fast closure at the packing station and a pull-tab tear strip that gives recipients a clean, damage-free opening experience. Sold in cases of 100, parcel-friendly for small-parcel replenishment.
