Built to Handle the Postal System.

Postal lock bottom boxes feature a secure interlocking base specifically engineered for products that must survive postal handling and distribution. The locked base resists opening under the stresses of transit, making it the preferred choice for direct mail packaging, e-commerce dispatch, and automated high-volume packing operations.
