Not all “Smashproof” mug boxes are created equal.
They can look almost identical online. So instead of simply telling you ours are stronger, we put them to the test.
Same mug.
Same height.
Same conditions.
But are they both smashproof? Watch our video to find out.
Looks similar. Feels very different.
From a product photo, most smashproof mug boxes look much the same. Side by side, the differences in construction and rigidity are much easier to see.

11oz Smashproof Mug Mailing Boxes
Heavy-duty protective packaging designed specifically for safely shipping standard 11oz ceramic mugs.
Our 11oz Smashproof Mug Mailing Boxes are designed specifically for sending ceramic mugs safely through the post, without the need for bubble wrap, void fill or an additional outer box.
Developed with a leading UK cardboard manufacturer, each mailer uses a strong corrugated construction together with our protective ‘angel wing’ internal flap design. Once assembled, the folded structure creates multiple layers of protection around the mug and helps keep it securely positioned during transit.
Unlike many lightweight mug mailers, these boxes have been designed with rigidity and protection in mind. We've put them through our own real-world drop testing with ceramic mugs inside - including drops from up to 6ft / 1.83m -— so you can see how they perform rather than simply taking our word for it.
The clean pure white exterior gives your orders a professional finish and provides an excellent surface for shipping labels, stickers or your own branding. The boxes arrive flat-packed for efficient storage and are quick to assemble when required.
No additional protective packaging is needed. Simply assemble the box, place your standard 11oz mug upright inside, close the protective flaps, secure the closing flap with a small piece of packing tape and apply your shipping label.
Available from individual boxes through to full pallet quantities, they're suitable for everyone from occasional personalised-gift sellers to businesses dispatching hundreds or thousands of mugs.

Protection comes from the design.
Our Smashproof Mug Boxes are designed to protect the mug from more than just the outer walls of the box.
The internal ‘angel wing’ flaps fold around the mug to help keep it securely positioned and create additional layers of corrugated board around vulnerable areas during transit.
The result is a compact mailing box that provides protection without the need for bubble wrap, loose fill or an additional outer carton.
- Keeps the mug securely positioned
- Extra folded protection around vulnerable areas
- No bubble wrap or void fill required
- Compact self-folding design
The cheapest box isn’t always the cheapest way to ship a mug.
A broken mug costs more than the blank itself. You also lose the print, labour, packaging and postage — and then have to pay to replace the order.
Shipping mugs at scale?
