Custom Mailer Boxes FAQ

How do I measure the interior dimensions of my mailer box?

With the box open toward you, here's how to get the correct measurements for the inside of the box:

  • The length is measured from the left to right side of the box.
  • The width is measured from the front to the back of the box.
  • The depth is measured from the top to the bottom of the box.

Will white ink show up on kraft corrugated cardboard?

We can arrange for a kraft-like texture to appear on the premium or standard white cardboard. You can contact our customer service for more information. Otherwise, white ink will appear brown if you select kraft as your corrugated cardboard color.

Can I print on the inside and outside of the box?

Yes, you can print your designs in full-color or black ink on the inside and outside areas of the mailer box. Printing on only one side of the box is also available, if you prefer.

I found a QR code on my custom mailer boxes. What is it?

We use the QR code to speed up the production of your custom boxes. It also helps us track your order better. Don’t worry, the QR code won’t affect the design since it’s not visible once the box is assembled.

When will I receive my boxes?

Production and delivery times vary based on your order size. Once your artwork is approved, it takes 4 -15 business days to produce your full-color boxes. Black ink mailers take 10-12 business days for production. Transit-time will be 2-5 business days from there depending on the shipping method you select at checkout. If you need the mailer boxes sooner, Rush options may be available with production times of 4 - 8 business days. Read more about our production and turnaround times.
