The 11" x 13-1/2" Tab-Lock White Flat Mailers are made from strong chipboard and require no additional stiffeners to protect your documents. Sold 100 per Case.
The rigid chipboard construction of these Staples StayFlat mailers allows you to ship magazines, documents, marketing materials, or other flat media without bending, folding, or creasing. Locking tabs ensure the contents stay safely inside, and the white exterior is a great surface for writing shipping information without the use of labels.
