Elevate the Unboxing Experience With Custom Mailer Boxes

Create mailer boxes that stand out as soon as they arrive at your customer’s doorstep. Your subscription boxes, e-commerce deliveries, or promotional kits can readily engage with a colorful and crisp representation of your brand on the packaging.

Custom mailer boxes provide all the advantages of having your products shipped. These lightweight boxes are easy to assemble and affordable to have shipped. Made of durable corrugated cardboard, each mailer box can withstand external forces even during transit.

Sturdy and Stylish Materials for Custom Boxes

Your mailer boxes will be printed on durable corrugated cardboard. After protecting your items during transit, the box can be recycled in different ways after customers open the package. There are two thicknesses depending on the size of your box: the thinner 1/16 E-Flute and thicker 1/8 B-Flute.

We offer two colors that suit everything, from a minimalist to a rustic design:

Standard White Corrugated Cardboard

  • The cost-efficient, go-to choice for this box type
  • Comes in a smooth, uncoated finish
  • Thick enough to withstand multiple handlings and deliveries
  • Now enhanced with HD Print

Premium White Corrugated Cardboard With Glossy Ink

  • Complement your design with a radiant white background
  • Perfect for designs with vivid details and colors
  • Available in Glossy Print or upgraded Satin HD Print

Kraft (Brown) Corrugated Cardboard

  • The default look and finish of corrugated cardboard
  • Perfect for natural or rustic-themed designs or products such as organic items
  • Upgraded to HD Print with no extra charge

HD Print

Combines lithographic quality printing with the ease and simplicity of digital.

  • Sharper, clearer details compared to digital prints
  • Water-based inks comply with the most stringent global food safety regulations and industry guidelines
  • Finished with an aqueous coating for a consistent look and premium feel

Frequently Asked Questions About Custom Mailer Boxes

Can I order a sample mailer box before committing to a larger quantity order?

Yes, you can order 1 mailer box that will be printed according to your size, material, design, and other printing specifications. Production time of samples will take between 5 business days.

How can I accurately measure the interior dimensions of the mailer box?
  • Open the box and make sure the interior is facing you while you make the following measurements:
  • The length is measured from the left to right sides of the box.
  • The width is measured from the front to the back sides of the box.
  • The depth is measured from the top to the bottom of the box.
What are the minimum and maximum interior dimensions for custom mailer boxes?

We made our sizing range as wide as possible so our mailer boxes can accommodate an extensive array of items: 

  • Length: 3" – 25" 
  • Width: 2" – 25" 
  • Depth: 1" – 15" 
Do you offer design proofing?

Yes. Before we process your order, the design will undergo a 15-point prepress inspection to ensure that it’s free of any technical errors. We provide this for free for all product orders. 

How long does it take to print my order?

Sample box orders only take five business days to produce, while orders of more than four boxes take between 10-15 days. Take note that these turnaround times don’t include delivery. You can check the estimated shipping date by entering your ZIP code in the order summary. 

How can I reorder?

There are two ways to reorder a previous order: through the website or by email. 

  • Website – Select “My Account” in the upper right corner and click the “Order and Proofs” tab to access your order history. Click the previous order you want to duplicate. 
  • E-mail – Forward the confirmation email of your previous order to Don’t forget to note changes or revisions if there are any. We’ll send you an updated price for approval.  
Do you offer wholesale prices?

Yes. Purchasing mailer boxes in bulk will bring down the price per unit, resulting in a lower total cost. 

Did you add the QR code I found on my custom mailer box on purpose?

Yes. This was added after proofing to improve your custom order’s trackability during printing. The code will always be located on a hidden area once the box is assembled, so you don’t have to worry about it affecting your original artwork.
