We make it a highlight of each delivery with our Custom Display Mailer Boxes. With 11 sizes available, each designed around USPS Tiered Shipping Rates, the boxes offer ample interior room without adding excess weight. Create your custom packaging from our free online design tool and ready-made templates. Not sure how it will look? Order a Quantity of 1 to see a real-time printed proof before placing your full order.

Inks

Every box is digitally printed in full CMYK color and cured with UV ink, giving your artwork a crisp and slight gloss look that will not fade or peel on the way. No minimum order requirement and fast turn-around times, you can create display boxes on demand, whether you need one box or a thousand. You have access to hundreds of free templates from which to design a mailer box that will impress your clients the moment they open it.

Our Materials

Every mailer is built from sturdy E-flute corrugated cardboard that is tough enough to withstand the bumps and drops of shipping. Our boxes are printed on a bright white exterior and interior, rather than kraft, so your colors stand out, not be muted by brown cardboard.

Fluting: E-flute Exterior material: white Interior material: white

Sizes

9.5″ x 7.75″ x 4″ is our most requested size, optimized for USPS Tier 2 shipping rates.

Inside dimensions: 9.5″ x 7.75″ x 4″ Outside dimensions*: 10.188″ x 7.875″ x 4.188″ Weight: 8 ounces USPS Tier: .194 ft3, Tier 2

*Outside dimensions are approximate and may vary slightly depending on assembly.

Our Process

We print your artwork in the best quality, 4 color CMYK process ink with UV curing. This ink is super-durable, won’t rub or fall off when touched. Our printers are calibrated according to SWOP, but because no two digital printers are exactly alike, we cannot guarantee a PMS match. Explore our proof options below to see what you’ll get before you place your order.

Designing Your Box

Our online editor and collection of premade box templates make creating your own packaging even easier than before. Check out our video to learn more about creating your own box.

Proof and Sample Options

If you are worried about missing a proof, here are three ways you can check the quality of your design before making a full run.

Color Test: You can take a color test to find the exact shade you are looking for with our color sampler. If you can’t find the color you need, just chat with one of our customer service representatives and we’ll see what we can do.

You are a rewriting assistant. Order a box of 1 for a proof. This will allow you to see your art printed on the actual box and will be the most effective way to see your artwork in print. Turnaround times will vary. Tell us if you have an urgency, and we’ll include it on your order.

Free Print or Blank Samples: For those that just want to feel the print and material quality or you just want an extra blank included with your proof order, please add a sample mailer box to your cart.

Product Guarantee

We are completely responsible for the quality of our mailer boxes. If you are ever dissatisfied, please call us. Our terms and conditions cover our refund and reprint policies. Since every product is 100% custom, our customers are responsible for the art file. If you are concerned about how your product will look, we recommend ordering a proof before placing your full order.

Sustainability Promise

We value our role in supporting green and sustainable practices. We buy raw materials from suppliers certified to the Sustainable Forestry Initiative (SFI), the largest single forest standard in the world, through rigorous research. Each mailing box we produce is made with at least 50% recycled material.
