What Is a Mailer Box?
A mailer box (or roll end tuck front box) is a one-piece box with double side walls and a hinged lid whose front flap tucks inside the front wall. It folds together without glue or tape, survives the courier and opens like a gift, which makes it the go-to box for subscriptions and e-commerce.
Double side walls and locking tabs make a strong box with no glue or tape.
The lid’s front flap tucks inside the front wall, so it stays shut in transit.
Available in kraft or white corrugated, with a tear strip, insert or inside print.
Print outside and inside for an unboxing that customers share online.

The Mailer Boxes Style, Explained
Why Brands Choose Mailer Boxes
Custom mailer boxes are built to ship: double side walls, locking tabs and a tuck-in lid hold up in transit with no tape needed to close them. For e-commerce and subscriptions, wholesale mailer boxes turn the delivery itself into a branded unboxing.
Strong Without Glue
The roll end tuck front design folds the side walls over themselves and locks them into the base. That double thickness gives crush strength on every side, and the box ships flat until you need it.
Printed Mailer Boxes, Inside and Out
Full-color printing on the outside gets noticed on the doorstep; printing the inside adds a reveal when the lid opens. Printed mailer boxes can carry foil, spot UV or a soft-touch finish with no extra plate charges.
Kraft, White or Black Corrugated
Choose natural kraft or bright white E-flute corrugated for strength, or premium black board for a luxury look. Every option is sized to your product so it does not slide around in transit.
Eco-Friendly Mailer Packaging
Our corrugated board is fully recyclable and FSC-certified options are available, so eco-friendly mailer boxes can replace plastic mailers and void fill.
