Kraft Stayflats® Mailers in the 12 3/4 x 15 inch size are self-stiffening flat mailers manufactured from .036 kraft chipboard. The rigid chipboard construction eliminates the need for separate stiffener inserts, and the tab lock closure secures contents during transit without tape or additional fasteners.

These mailers are well suited for e-commerce fulfillment, retail distribution, print shops, and photography studios shipping documents, photos, artwork, certificates, and other flat materials that must arrive without bending or creasing. The lightweight chipboard keeps per-unit weight low, helping manage postage and carrier costs at volume.

Each mailer is sold in cases of 100. The consistent dimensions and self-stiffening design make this a practical stock item for operations shipping flat goods on a recurring basis. Ships via parcel carrier.
