What happens after you send it.
We read the specs
A real person checks whether the dimensions, board grade and quantity make sense together, and comes back with questions if anything is ambiguous.
You get itemised pricing
Unit cost at several quantity tiers, tooling if any, and freight to your door — plus a free dieline and a 3D mockup of the custom mailer box.
You approve the proof
Change anything you want at this stage — it costs nothing. Nothing reaches the press until you sign the proof off in writing.
We print and ship
Four to six working days from approval. Boxes arrive flat-packed, with free shipping across the continental USA.
The short version
- Send dimensions, quantity and artwork and you get a quote the same working day.
- Measure the product, not a box — we add clearance and board thickness ourselves.
- Shipping across the continental USA is free and already in the quoted price.
- Ask for a physical sample before your first production run.
What to include in your enquiry
Four details decide a custom mailer box price. Give us all four and the quote comes back the same day instead of after a round of questions.
| Send us | Why it matters | Example |
|---|---|---|
| Product dimensions | We size the box around the product and add clearance ourselves. Sending a box you already use bakes in someone else’s mistake. | 8 × 6 × 3 in |
| Quantity | Pricing moves in steps, not a straight line. Give a second number if you are weighing options and we will quote both. | 500 · and 1,000 |
| Artwork | Decides the print method and how many colours. A sketch or a competitor photo is enough to start. | Vector logo, PDF/AI |
| Deadline | Tells us whether a standard slot works or you need rush production. | “Live by 15 Oct” |
Where we ship & how long it takes
We manufacture in the United States. Freight is included in the quoted price rather than added at checkout, so the number you approve is the number you pay.
| Destination | Shipping | Total time from approval |
|---|---|---|
| Continental USA | Free, included in the quote | 4–6 days + transit |
| Alaska & Hawaii | Quoted per order | 4–6 days + transit |
| International | Quoted per order — tell us the country | Case by case |
| Rush production | Subject to press availability | Ask when you enquire |
Production time starts when you approve the proof, not when you place the order.
Samples, artwork and who to email
You can ask for a physical sample of your custom mailer boxes before committing to a production run — on a first order we recommend it, because a screen cannot tell you whether a box fits. Anything you send stays confidential: we do not use customer artwork in our own marketing or sample packs without asking first.
