Solid mailer, would take a beating!
Solid construction, really happy with this mailer. My product isn’t that chunky but this mailer would absolutely handle a decent thickness, weighty book or similar product with the way it expands. Grateful to HeapsGood people too for including a sample of another product I asked for too, super helpful for my next order. Thank you!

Perfect fit for my prodcuts
I am extremely happy with my rigid mailers! I was looking for something sturdy but lightweight, and just larger than my business's paper envelope, to post my prayer cards overseas and these are perfect! Thanks so much.

Amazing quality and works great
We use these for our business as a backing for fragile products. Unlike others we have used, these are sturdy but not too heavy - which is great when every gram counts with shipping pricing.

Rigid Mailer FAQs

A rigid mailer is the lovechild of a mailing box and a flexible mailer. Designed so they can pack flat and inconspicuous, or expanded into a box-like shape, while still protecting your fragiles.

These mailers can be shipped like any other Ecomailer, Padded Mailer or the like! No special treatment here. Bonus: The small and medium sizes can be used as AusPost Large Letters without the gusset expanded.

Our rigid mailers are 100% kerbside recyclable.

Now this depends on the size. Sending something small or flat? Our hard mailers or padded mailing bags will do just the trick. If your item is a bulkier or funnier shape, check out our Hex Wrap and Mailing Boxes.

Our rigid mailers have an expandable gusset on the sides, meaning they can pop up and out to fit bulkier items, like War and Peace.

What our rigid mailer has going for it is that aggressive corner protection. The expandable gusset angles outwards to ward off any bumps, knocks or package thieves. Your items are safe inside their cardboard fortress.

Books, small garments, or anything fragile - china, jewellery, egos. If it fits, it's ridgy didge.
