Mailer Boxes
Self-locking, tape-free mailers printed in full color inside and out. The unboxing moment your customers screenshot.
“Mailers arrived in nine days with the inside print exactly as proofed. Our unboxing videos finally look like the brands we admire.”
“The valve bags keep our roast fresh and the print quality is better than bags we paid twice as much for. Reorders take one email.”
Custom mailer boxes that earn a screenshot
A customer films their hands sliding open the lid, the magazine-style flaps fold back, and your logo is sitting right there on the inside panel. That clip ends up on a story, then a feed, then in front of a few hundred people who have never heard of you. A plain brown box never does that. A custom mailer box does it every week, and it costs a few cents more per unit than the boring option.
Mailer boxes are the self-locking, tape-free corrugated boxes you see on almost every direct-to-consumer order. The body folds up from a single sheet, the side wings tuck in, and the front lip slots into a die-cut slit so the whole thing snaps shut without tape or glue. That construction is why people love them. They open clean, they close clean, and the flat inside panels give you a full canvas to print on.
Who actually uses them
Skincare and cosmetics brands lean on mailer boxes because the unboxing is part of the product experience. Apparel and accessories ship in them because the box doubles as the gift wrap. Coffee roasters, supplement companies, candle makers, jewelry studios, subscription services, and electronics accessory sellers all run mailers as their default ecommerce box. If you sell something a customer ordered for themselves and you want the delivery to feel deliberate, this is the format.
Subscription boxes in particular live or die on the open. A branded mailer with printed inner walls and a tissue layer turns a monthly shipment into something members look forward to, which is exactly what keeps them from cancelling.
Materials and construction
Most custom mailer boxes are built from E-flute corrugated. E-flute is thin (about 1.5mm) but rigid, so it prints crisply and folds into clean edges without the chunky look of a shipping carton. For heavier or larger products, we move up to B-flute for more crush resistance. You can order them in:
- White kraft (a bright, smooth printing surface for full-color artwork)
- Natural brown kraft (the recycled, earthy look, printed with one or two colors or left raw with a logo)
- Full-color litho-laminated stock for photo-quality print across the whole box
The tuck-top style with self-locking wings is the standard. We also make roll-end front-tuck mailers and book-style mailers if you want a different open. Add a printed insert or a die-cut foam tray to hold the product in place and the box stops feeling like shipping and starts feeling like presentation.
Sizes and how to choose
Pick the box around the product, not the other way around. A mailer that is too big lets the contents rattle and forces you to over-stuff it with void fill. Too tight and the flaps fight you on assembly. Our standard mailer footprints start around 6×4×2 in for small items like jewelry or a single jar, run through 9×6×3 in for a typical apparel or skincare set, and go up to 12×9×4 in and 15×12×5 in for bundles and multi-item orders.
Measure your product at its widest point in all three dimensions, then add roughly a quarter inch of clearance plus room for tissue or an insert. If you are between sizes, size up slightly and fill the gap with branded tissue rather than cramming. We send a free dieline before printing so you can check the fit on screen.
Printing and finishes
This is where a mailer stops being a box. Print full color (CMYK) on the outside, the inside, or both. The inside print is the move most brands miss, and it is the cheapest way to make the open feel premium. On top of the print you can add:
- Soft-touch matte lamination (the velvety feel people associate with luxury)
- Gloss lamination for punchy, saturated color
- Spot UV to make a logo or pattern catch the light against a matte field
- Foil stamping in gold, silver, rose gold, or holographic
- Emboss or deboss for a raised or pressed logo you can feel
You do not need all of these. A soft-touch matte exterior with a foil logo and a printed inside panel already reads as a brand that cares.
Minimum order, turnaround, and how ordering works
Our minimum order is 30 units, which is unusually low for printed custom mailer boxes. Most wholesale suppliers push you to 500 or 1,000 before they will run a custom print, so testing a launch gets expensive. Starting at 30 means you can order a small batch, see how the box photographs and ships, and reorder once you know it works.
Production runs about 10 days from approved artwork. The flow is simple: send your logo and artwork (or a rough idea and we help build it), we return a free dieline and a digital proof, you approve, and we print. Pricing scales with size and quantity, starting near $0.78 per unit and dropping as the run grows, so larger batches and wholesale orders bring the per-box cost down meaningfully.
Sustainability
Corrugated mailers are already one of the friendlier packaging choices. The board is recycled-content and curbside-recyclable, and we print with water-based inks. Skip the gloss laminate and stick to kraft or uncoated white if you want the box to break down cleanly. If recycled stock is a priority across your whole order, look at our eco shipping boxes too.
Frequently asked questions
Can I get custom mailer boxes with my logo on a small run?
Yes. The minimum is 30 units, so you can put your logo on a printed batch without committing to thousands. That low floor is the whole point of how we price custom printed mailer boxes.
What mailer box sizes do you offer?
Standard footprints run from 6×4×2 in up to 15×12×5 in, and we cut custom sizes to your product's exact dimensions. Send us the measurements and we will recommend the closest fit.
Do you offer custom mailer boxes wholesale?
We do. Per-unit pricing drops as the quantity climbs, so a 1,000 or 5,000-unit run lands at a true wholesale rate while still being fully custom printed.
What about custom kraft mailers without full-color print?
A natural kraft mailer with a one or two-color logo is one of the most popular and most affordable options. It looks clean, recycles easily, and keeps cost down.
How are these different from a custom rigid mailer?
A corrugated mailer folds flat and is light enough for ecommerce volume. A rigid mailer uses stiff chipboard to keep flat goods like prints and documents from bending. Different jobs.
