When you search for mailer boxes near me, you usually want boxes today. A post office or Officeworks will get you through an emergency, but as soon as you need a particular size, your logo on the box or more than a handful at a time, you run into their limits.
Here is how the main options compare, and how to brief a supplier so you get the right mailer the first time.

Why “near me” matters less than you think
The price on the box is only part of what you pay. Freight from interstate or overseas is added on top, and on small orders it can cost more than the boxes. Overseas print runs also take weeks to arrive, so you end up holding more stock just to avoid running out.
An Australian manufacturer with a known lead time is often the cheaper option once everything is counted. Our standard turnaround is 2 to 7 business days from final artwork and size approval, plus freight to your door, or you can pick up from our factory in Mount Barker, SA.
Choosing the right mailer box
1. Size it to the product
Measure the inside dimensions you need: length, then width, then height. Allow a 3 to 5 mm buffer for a snug fit. Couriers and Australia Post charge on actual weight or cubic weight, whichever is higher, so a box that is too big costs you every time you post it.
2. Pick the right board
| Board | Thickness | Holds about* | Good for |
|---|---|---|---|
| R flute | 2 mm | 2 kg | E-commerce mailers and subscription boxes. Smooth surface for sharp print. |
| B flute | 3 mm | 4 kg | Medium-weight retail items and standard shipping. |
| C flute | 5 mm | 8 kg | Shipping cartons that need cushioning and stacking strength. |
| BC flute (double wall) | 7 mm | 12 kg | Heavy, fragile or high-value goods. |
*Weight capacities are a guide only.
3. Choose a colour
Brown kraft hides scuffs and suits a natural look. White makes printed colours bright and sharp, but shows marks from the post. Matt black looks premium and hides transit marks well.

When custom mailers make sense
Plain boxes are fine for one-off sends. Custom mailers start paying for themselves when:
- You run subscription boxes, where the unboxing is part of what customers pay for.
- You sell online regularly and want every parcel to look like your brand.
- No stock size fits well, so you are paying for void fill and extra postage.
We make custom mailer boxes in short runs, with low-volume full-colour printing done in-house and no upfront tooling cost.
Questions to ask any supplier
- What is the minimum order? Make sure it matches how many boxes you actually use.
- What is the lead time from approval to my door? Not just production time.
- Can I get a sample first? Worth it before any large order.
- What board grade is it? Ask for the flute type, not just “single wall”.
- Can you quote my exact size? A box made to fit saves on void fill and postage.
