Convenience & confidence
With self-locking boxes (also known as crash-lock boxes), the bottom of the box automatically locks into place to ensure your products are secure during transit and storage. And with complete inside and outside printing available, you can really make your self-locking postal boxes stand out and get noticed everywhere they go.

Great for shipping & storage Self-locking boxes are ideal for storing and shipping larger or multiple products. Available in 3 sizes in your choice of white or brown kraft E-flute cardboard, crash-lock postal boxes are a go-to for sample packs, corporate gifts, subscription boxes and more. What’s more, if you’re not sure about the size or look of your boxes, you can order 1 to start and then order more.

Intuitive design process To get started, upload your design or brand logo. Once you’ve done that, you’ll be able to add backgrounds, colours or text to create your unique look. With our new 3D design studio, you can check your design from every angle before printing to make sure it’s what you want. After that, we’ll take over. Your self-locking postal boxes will be professionally printed, packaged and arrive ready to box out the competition.
