Flat Corrugated Boxes 14123

These flat corrugated boxes arrive ready to fold into rigid mailers. Each unit measures 14 3/8 by 12 by 3 1/2 inches and is made from Kraft material. The pack contains 25 boxes for bulk shipping needs.

Single-wall construction limits

The single-wall corrugated board protects contents against normal handling but is not rated for heavy or fragile items without extra cushioning. Stacking strength decreases if boxes become damp or are overloaded. Consider double-wall alternatives for heavier shipments.

Pack quantity of 25 units

The box count of 25 determines whether this pack matches your mailing volume. Smaller operations may find the quantity excessive while high-volume shippers can order multiple packs. No smaller or larger pack sizes are listed for this model.
