Shipping made simpler
Why use multiple types of packaging when you only need one? Our square mailer boxes are made from sturdy, white B-flute corrugated cardboard, so all you have to do is stick a shipping label on them and they’re ready to go. The internal fluting protects your goods by absorbing any bumps and thumps they may receive along the way.
Corner-to-corner printing
These won’t be just any square cardboard boxes, because you’ll be able to design and print the entire surface, inside and out. What better way to make your brand memorable from every angle? Our custom square mailer boxes are great for smaller subscription orders, apparel, books, stationery, beauty products and more. If you’re looking for boxes with a larger capacity for bigger products or combination orders, check out our mailer boxes.
Intuitive design tools
Maybe you’re new to designing, or maybe you already have a unique logo or design of your own. Using our 3D design studio , you can create the look you’re searching for. Choose from one of our many custom design templates or upload your own logos, images, fonts or patterns (be sure to remove any die-lines to prevent them from getting printed). The 3D view lets you see what your boxes will look like in real life. Just make sure you remove the die-lines from your uploaded image before printing, otherwise they will appear on your final product. And that’s it, just sit back and wait for your professionally printed square mailers to arrive.
