Product Mailer Boxes
Product mailer boxes built around one specific item rather than a size range — cavity, clearance and closure all set by what goes inside.

- Fitted board or foam inserts where the item needs holding
- Removes void fill from the packing bench entirely
- E-flute or B-flute depending on weight
- From 50 units with a free dieline and 3D render
- 4–6 working daysClock starts at proof approval
- Artwork checked firstBleed, folds and colour build
- Nothing prints unapprovedYou sign the proof first
- Curbside recyclableUnless you choose a laminate

product mailer boxes.
Send the dimensions of the product rather than a box you already use — we add the clearance ourselves. Itemised pricing comes back the same working day.
- Priced at several quantities, so you can see where the curve flattens
- Print-ready dieline and a 3D render, at no charge
- We flag it if a smaller dimension would cost you less

Most packaging is bought as a size that is close enough. A product mailer starts from the opposite end: the item is measured, and the box is drawn around it. That changes what the box costs to run and how the product arrives.
What “close enough” costs
A box a size up from ideal carries three ongoing costs. You buy filler to take up the gap. You store and handle that filler. And you pay dimensional weight on the empty volume, on every order, indefinitely.
None of them is dramatic individually. Together, on a product shipping in any real quantity, they routinely exceed the difference between a stock box and a bespoke one.
When an insert is the cheaper answer
If the product needs holding still — anything fragile, anything with a lid that can pop, anything that arrives looking wrong when it has slid to one end — a fitted insert usually costs less than the volume of loose filler it replaces, and it works better.
It also does presentation work. An insert that stops movement in transit is the same insert that presents the product face-up when the lid folds back. You can see this done well on mailer boxes with inserts.
One size or several
Each size needs its own die and its own setup, so two sizes is close to two jobs. Sometimes that is still right — a single compromise box across very different products means most of them ship badly. We will price both ways so the trade-off is visible rather than assumed, and our note on how packaging is priced explains why the second size costs less than the first.
Frequently asked questions
What do you need from me?
The product’s length, width and height at its widest points. Not the box you currently use.
Can you work from a sample?
Yes. Send the product and we will measure it and build the dieline from that.
Is a bespoke box much more expensive?
The die is a one-off cost and it is kept on file for reorders. Per unit, a right-sized box is often cheaper to run once freight is included.
Send the product, not the box
We will measure, add the correct clearance, and return a dieline with a 3D render so you can see the fit before committing.
How we build product mailer boxes.
Measured from the product
We size the box around what goes inside and add the clearance it needs. That removes void fill you would otherwise buy and dimensional weight you would otherwise pay on every order.
Colour that behaves
Process CMYK or a Pantone spot match, outside and in. We tell you how a colour will sit on kraft before the run, not after it.
Board matched to the load
E-flute, B-flute or double wall depending on weight and fragility. We will talk you down a grade as readily as up one.
Assembles in one motion
One-piece construction with a front-tab lock. No tape, no gun, and seconds rather than minutes at the packing bench.
Recyclable as standard
Kraft and corrugated go in the curbside bin with water- and soy-based inks. Plastic lamination changes that, and we say so when you ask for it.
Fifty is a real run
Enough to prove a design before committing to thousands. Pricing steps down at 250, 500 and 1,000 as setup cost spreads.
Customization options
Board, print method and finish are three separate decisions, and each one moves the price. We will tell you which are worth paying for on your product and which are not.
