Custom Ear Lock Mailer Boxes Sized to Your Product

What is an ear lock mailer box?

Picture a shipping box that closes like a gift box. That is the idea here. It is cut and scored from a single sheet of corrugated board.

When you shut the lid, two ears on its sides slide into slots and lock. The front flap tucks under to finish the job. You can browse the wider set of mailer and postal box styles to compare it with other closures.

Does it make a good unboxing?

Yes. The lid lifts in one motion and stays upright, so the inside print is the first thing a customer sees.

Because the walls are folded and not cut, nobody meets a rough edge. Add a sheet of tissue, a small card and a snug insert. That is often all a gift box needs.

A lid message in one color over a printed pattern inside looks sharp on camera. That helps if you send boxes to creators who film the opening.

How strong are the double side walls?

Each side wall folds back over itself before the lid closes. You end up with two layers of board down both sides.

That makes the box stiffer along its length and hides the raw board edge. For heavier items, compare the fold style with double wall boxes for heavier loads. We do not publish load ratings. Tell us what you are shipping and we will suggest a board.

Which board should I choose for an ear lock mailer?

Board thickness changes how the folds feel, how the print looks and how much the box can carry. Our flute guide for corrugated board explains each option in more depth.

What size ear lock mailer do I need?

Start with the product. Measure its length, width and height, then add any insert, tissue or card that goes in with it.

Give us the inside size in inches, or in millimeters if you prefer. Folded walls use up a little room at the top edge, so tall items need some extra height. If you are not sure, send the product dimensions and our designers will suggest a size. The steps in how to measure a box help if you are doing it yourself.

What print and finishes can I add?

You can print plain, one color, two color or full color CMYK. Print goes outside, inside or both. A pattern on the inner walls with a short message on the lid is a popular layout.

For finishes, pick uncoated kraft, matte or gloss lamination, spot UV, foil stamping or embossing. Foil on a dark lid looks especially rich. Try placements in Design Your Box and our designers will help prepare the files at no charge.

Artwork wraps over the folds on this style. The top edge of each side wall rolls over, so a band of color shows inside and out. Your free proof marks every fold line, so you can spot a logo sitting too close to an edge before we print.

Can customers reuse or return the box?

They can. With no glue on the lid, the box opens and shuts many times and keeps its shape.

Customers tend to keep them for cables, cards, jewelry or craft supplies. For returns, the buyer repacks the item and adds a strip of tape or a label. If returns are common, print a short note inside the lid. Our page on reusable boxes for repeat use has more ideas.

Kraft board handles wear well. A laminated finish wipes clean if the box sits on a shelf.
