Staples® Self-Seal White Flat Mailers are strong to protect photos and documents during shipping.
Staples® 9" x 11-1/2" Tab-Lock White Flat Mailers are made from strong chipboard and require no additional stiffeners to protect your documents. Sold 100 per Case.
These Staples StayFlat mailers are 9 inches wide and 11.5 inches long, so they fit all types of letter-size and smaller documents. They hold standard-size documents tightly, preventing them from slipping around and reducing the chance of edge damage in transit. Use these mailers for individual photos or small stacks of paper; they flex slightly to accommodate your items.
As the name suggests, these Staples StayFlat mailers are designed to keep their shape during mailing. Made from rigid chipboard, these mailers resist crushing or bending, even when they're tossed, handled, and slipped through mail slots. Since the chipboard is lightweight, the mailers help you cut back on postage costs too.
Don't worry about packages getting lost in the mail—each of these mailers has a crisp white surface that contrasts strongly with all ink colors to create high-visibility addresses. You can also apply a standard mailing label for a professional look.
