The main types of mailer boxes are the roll-end tuck-front mailer, the tuck-top mailer, the auto-lock bottom mailer, the front-lock mailer, and the rigid mailer. The Best Price Boxes makes them with no minimum order and beats any written quote on the same specs. Which one you pick comes down to what ships inside and how it should feel when opened.
The styles, one by one
| Style | How it closes | Best for |
|---|---|---|
| Roll-end tuck-front | Lid tucks into a front slot, side walls roll in | Apparel, subscription boxes, lightweight items |
| Tuck-top mailer | Lid tucks into the front wall, often with dust flaps | Cosmetics, candles, small gifts |
| Auto-lock bottom | Pre-glued bottom pops into place | Heavier items, faster packing |
| Front-lock | Tab locks the lid to the front panel | Items that shift in transit |
| Rigid mailer | Thick wrapped board, magnetic or lift-off lid | Premium unboxing, gift sets |
Most corrugated mailers are made from E-flute or B-flute board, and the choice matters. E-flute is thin and prints cleanly, B-flute is thicker and protects better. For anything over a pound or two, I lean toward B-flute or a sturdier build.
Tuck-front or tuck-top
People mix these up all the time. A tuck-front mailer has its lid tuck into a slot on the front, which gives a clean look and a firm close. A tuck-top mailer has the lid tuck at the top edge of the front wall, which is slightly easier to pack. Both open like a book. If you are choosing for a product that may be opened by customers repeatedly, a tuck-front closes more securely.
For the plain version, see our tuck-top boxes. For a closer read on the format, our guide to what a mailer box is covers the basics.
Corrugated or rigid
Corrugated mailers ship directly. They survive parcel carriers without an outer box, which saves packaging cost and weight. Rigid mailers feel heavier and nicer, but they usually go inside a shipper carton, so you pay twice for packaging. If the unboxing is the point, go rigid. If the box is simply the shipping container, go corrugated. Look at luxury mailer boxes for the premium end.
How to size a mailer
Measure the product’s length, width, and height, then add room for any insert or tissue. Use interior dimensions in that order. Too much empty space lets the product slide around; too little and the lid bows. If you are unsure, send the product measurements and we will recommend a style.

Questions buyers ask
What are the main types of mailer boxes?
Roll-end tuck-front, tuck-top, auto-lock bottom, front-lock, and rigid mailers. Each closes differently and suits different products. Corrugated types ship directly; rigid types are more for presentation.
Which mailer box is best for shipping?
Corrugated mailers, especially auto-lock bottom or roll-end tuck-front styles. They are built for parcel shipping and need no outer carton for most products.
Can I order one mailer box to test?
Yes. There is no minimum order, so a single box is enough to check fit and strength before ordering more.
What is the difference between E-flute and B-flute?
E-flute is thinner and prints more cleanly. B-flute is thicker and protects heavier or more fragile products better. Tell us the weight and we will suggest the right one.
Can I print inside the box?
Inside printing is commonly offered on mailers. Ask us to confirm for your spec.
