A variation of our four flap enclosure, the adjustable four flap enclosure offers flexibility for storing various depths of materials. The sturdy 20 point interior four flap and 60 point exterior folder give added protection for heavier materials. The 1/4, 1/2, 3/4 and 1 inch scores let you choose the thickness your enclosure needs.
To store materials, open the folder and all four flaps. After determining the thickness of your materials, fold each flap on the appropriate score. Place your document in the center and close the bottom, top, right and left flaps. The final flap can be secured with enclosed VELCRO® dots.
