    This natural brown corrugated cardboard is what most of us think of first when we imagine a box. This material provides an eco-conscious feel that holds dark colors well and provides a simple and modest aesthetic for any package. Kraft material also has the highest recycled content of any material making it the most eco-friendly.

    Essential White

    Our essential white corrugated cardboard material is a cost-effective classic for custom branded box creation. This standard white board with a low shine offers a dependable canvas for showcasing any colors, logos, text or design elements.

    Magic White with High Definition Print

    For a box that’s clearly built to impress, select Magic White for your material and let our HD printers do the rest. This premium corrugated cardboard feels smooth to the touch, looks lusciously glossy and provides photo-quality prints you never thought possible on subscription boxes or custom packaging.

    Box Measurements: All measurements are done from the inside.

    Mailer Material is E flute currigated cardboard.

    Printing Options

    Make your custom packaging look great from every angle with our two-sided four-color printing option. Or you can also keep things simple with one-sided four-color printing.

    If you have your own design files ready to print, just open the design tools to download a die-line template matched to box type and size and upload to begin. BoxGenie will review our order, reach out with any questions, and quickly get your custom packaging printed.

    And you can always use our online design tools to choose patterns, colors and fonts that work for your brand. Our 3D tools let you see every angle down to the dust flaps and corners.

    Please note that your choice of material greatly impacts your color vibrancy and printing precision. For darker colors over a natural brown, choose Kraft. To get a full spectrum of colors that pop, choose Essential White. For photo-quality images and the most premium look and feel, Magic White material gives you the HDPrint quality you need.

    You may cover your box with as many colors or designs as you like, all for the same cost.

    Best Practices & Help

    Here are a few tips from our design and product teams on designing your box:

    • Always convert to CMYK before uploading files as this allows tighter control over your colors and images.
    • All text should be at least 8-point in size and use bold colors made up of no more than one or two inks (C, M, Y or K).
    • Choose your custom size based on interior measurements.
    • Include at least a 0.25-inch bleed when graphics extend past die-line.
    • Lines in a solid or dark color should be no thinner than 1 point.
    • Download our templates here if you prefer to create your own box design from scratch.

    FAQs - Custom Mailer Boxes

    Why do you have a minimum of 100 boxes per order?

    We’ve been in this business for a long time (nearly five decades, in fact). During that time and handling countless orders we’ve learned a lot about what it takes to optimize our operations to make the best use of our time and resources. We’ve also figured out the best tricks for saving our customers money on every order. One of these tricks is finding that perfect number that can keep prices down for you and production optimized for our team.

    We offer up a first-time buyer coupon code that, in most cases, will make the price on your order of 100 boxes on BoxGenie lower than what you would pay when ordering a smaller amount on other sites. We do this because we are confident that you will love your boxes and want to keep ordering from BoxGenie forever!

    How long will it take to get my boxes?

    You will receive emails from BoxGenie along the way letting you know when your order has been received and been printed.

    Product Time:

    We aim to review, process and print your order within 6-10 business days.

    Shipping Times:

    Your estimated shipping times will be based on whatever shipping method you choose when placing your order. Shipment orders timelines are typically estimated in business days. For example, if selecting UPS Ground, you’ll find that there is no guaranteed delivery window available. Rough estimates based on experience finds the UPS Ground delivery typically takes between 4-7 business days to arrive, or potentially less based on your location. Our production facility is based in Kansas City, MO, so the closer you are to us the shorter the shipping time.

    If you need your order by specific day or business days, we advise that you select a guaranteed delivery option (such as UPS 2nd Day Air, UPS 3 Day select, etc.)
