5L X 4W X 2H Inch Tuck-Top-Snap-Bottom White Mailer Single Wall - 3 Ply

Four Die Cut flaps form the bottom panel. To set up the box, just fold the largest bottom panel first, then the two end panels. When the remaining bottom panel is folded and pressure is applied near the center, the flap “snaps” into the slot created by the other panels. The style is convenient for small-volume shippers. As the bottom is not completely sealed, these may not be suitable for heavy products.
