Mailer Boxes

Custom mailer boxes are self-locking corrugated boxes that close without tape, ship flat, and carry your branding inside and out. E-flute suits lighter products and B-flute suits heavier ones. Every box is printed to your exact size. If your products arrive crushed, your packaging looks like else, or your team loses minutes taping every order, the box is the problem. The Custom Boxes supply branded custom mailer packaging boxes in your exact size, printed inside and outside, with minimums that suit a growing business. Brands that want wholesale customizable mailer boxes without a huge first order can start small and scale up.

The Packaging Problems Mailer Boxes Solve

Most online brands run into the same few problems.

  • Products arrive crushed or scuffed, which means refunds and bad reviews
  • A plain brown box makes your brand look like every other seller
  • Taping and sealing every order slows your packing line
  • Oversized boxes waste money on filler and freight
  • Printed colors do not match your brand

A mailer box answers most of these in one step. It holds shape, locks without tape and carries your brand on every surface. A self-locking style help your team pack mailer boxes faster, there is no tape to cut or seal. Mailers ship flat, so they take little storage space until you need.

Mailer Box Styles and Closures

The closure decides: how fast the box packs, how it looks when opened and how well it stays shut.

Style

How It Closes

Best For

Tuck top mailer

The lid tucks into a slot at the front, no tape needed

Everyday online store and subscription shipments

Roll end tuck top

Rolled sidewalls add strength, and the lid tucks into the front panel

Cosmetics, apparel, and products that need a clean, rigid look

Tuck end auto bottom

The bottom locks into place as the box is opened

Faster packing for larger daily volumes

Tear strip mailer

A perforated strip opens the box in one pull

Shipments where tamper evidence matters

E-Flute or B-Flute Corrugated

Flute is the wavy layer inside corrugated board. Its height sets how thick, stiff, and printable the box is. Thickness are approximate.

Flute

Approximate Thickness

Best For

E-flute

1/16 in (1.6 mm)

Small and medium mailers, smooth print for cosmetics and apparel

B-flute

1/8 in (3.2 mm)

Larger or heavier items that need more crush resistance

E-flute prints smoothly and stays compact. So it suits lighter products. Larger or heavier products usually do better in B-flute.

Mailer Box Sizes

Sizes are listed by inside length, width, and height. Measure your product, then leave a little space for an insert or tissue. A snug fit stops movement in transit, and a box that is too big costs more to ship.

Size

Typical Range (inches)

Common Products

Shoes, bundles, home decor, electronics

Every box is made to custom dimensions, so you are not limited to these ranges. Read our guide to standard sizes and dimensions for mailer boxes if you’re on a starting point.

Colors, Kraft, and White Corrugated

Your material choice sets both the look and the prices. Natural kraft is the lowest cost and the most recyclable. Our white corrugated board gives you clean artwork.

That matters for colored mailer boxes wholesale orders. Pink mailer boxes, for example look muted on brown kraft, so most brands print a solid pink over a white liner. Black tuck top mailer boxes come from black kraft or a full black print and suit premium cosmetics and apparel. White corrugated mailer boxes wholesale are the easiest for any bright color.

Customized cardboard mailer boxes can be cut to any size and finished with windows, foil or embossing. Bux board or cardstock suits lighter products.

Printing and Finishes

Add your logo & artwork on the outside, and save the inside lid for a thank you note, care card or QR code.

We print with CMYK and PMS color matching using digital or offset printing. Finishes include matte, gloss, soft touch, spot UV, foil stamping, embossing and debossing.

Inserts That Keep Products in Place

Loose products shift and abrasion. Custom mailer boxes with inserts hold the item still and look finished when they open. For fragile or high value items, see our boxes with foams.

Cookie mailer boxes need a fit, a tray or dividers to stop breakage, and a liner such as parchment or bakery paper inside the box. Tell us what you ship and we will suggest an insert.

Eco Friendly Mailer Boxes and Sustainable Design

More customers notice how a brand ships. Eco friendly mailer boxes start with the material. Kraft and corrugated are paper fiber and recyclable, and soy based and water based inks are available.

Sustainable mailer boxes design goes further than material. Size the box to the product so you need less filler, skip extra coatings, and print fewer colors. Browse our eco friendly boxes for more options.

Looking for the Cheapest Custom Mailer Boxes With Logo?

Price is the first filter for small brands, but the lowest quote is not always the lowest cost. A box that fails in transit costs more than one that costs a little more to print.

  • Pick a size close to your product so you do not pay for extra board
  • Use E-flute kraft where the weight allows
  • Print one or two colors instead of full coverage
  • Skip optional finishes such as foil and embossing
  • Order a larger quantity, since the price per box drops as the run grows

Custom printed mailer boxes in bulk bring per box price down and low minimum. Let you test a design before you commit to a large run.

Frequently Asked Questions

A single platform to manage your end-to-end packaging workflow

Below you'll find answers to some common questions around creating a custom box. Every order is little different though, so don't hesitate to reach out with anything else you might be wondering.

Mailer boxes are corrugated boxes with a built in tuck or locking closure, used to ship products without tape and present them well. They suit online stores, subscription kits, and gifting, and they ship flat until assembled. Printing on the box turns each delivery into a branded unboxing.
Choose E-flute for small to medium, lightweight mailers where smooth print matters, and B-flute for larger or heavier products that need more crush resistance. There is no single best choice because it depends on product weight and box size. Share the product details and we will recommend the right flute.
Sizes depend on your product. Mailers range from small boxes for jewelry and lip gloss to large boxes for shoes and home decor, and every box can be made to custom dimensions. Measure the product's length, width, and height, add room for any insert, and we will confirm the best fit on your proof.
Yes. Inside printing is available with the same CMYK and PMS color options as the outside, so you can print a full pattern, a message, or instructions on the inside lid. Ask for a proof to see how the inside artwork lines up when the box is open.
A mailer box has fold in panels and a tuck or locking closure, so it seals without tape. A regular shipping box, often a regular slotted container, has flaps that need packing tape. Mailers suit branded, lighter deliveries, while shipping boxes suit heavier freight and bulk shipments.
Yes. Foam, die cut cardboard, and paper inserts can be cut to your product's shape. Foam suits fragile or high value items, while cardboard and paper inserts keep costs lower for sturdier products. Share a sample or the product dimensions and we will suggest the right option.
Poly mailers are light and low cost, but they offer little protection and suit soft, non fragile items. Boxes protect fragile products, hold their shape, and give customers a branded unboxing. Choose a poly mailer for apparel basics and a box when protection and presentation both matter.
