The ideal packaging for mailing flat and lightweight products that are too large for an envelope but will fit through a mailbox slot.
Our sturdy corrugated cardboard mailbox boxes protect the contents and look professional. With a height of 2.8 cm they will fit through the slot of every standard mailbox. Perfect for webshops because the postman doesn’t have to ring the bell, which means your mailing costs are considerably lower.
The single layer corrugated cardboard and reinforced sides make these mailbox boxes extra strong so your products are also protected against jolts and knocks.
No tape required
Thanks to the top flap with a convenient side-insertion the box can be closed securely without tape. The recipient opens the box very easily from the top.
Your own printing
These white mailbox boxes can be printed with your own logo, text or image. They are available in five different sizes ranging from just 11 x 11 cm to just slightly smaller than the maximum size that can be posted through the slot in a standard mailbox.

Weights and measures
SendProof Packaging is our quality label for a complete and well-considered offering of mailing packaging. Good packaging means more efficiency in the chain, less damage, fewer returns and, therefore, lower costs. That is what SendProof Packaging stands for.
Safe and efficient
SendProof’s products are suitable for mailing both food and non-food products safely and efficiently. We offer the right mailing packaging for every product; from books, cosmetics and bottles of wine to fresh vegetables, meat and fish. Maximum product protection, optimum user convenience, cost efficiency, experience and low environmental-impact are key criteria for the SendProof range.
Achieve savings with professional products
In addition to a complete range of standard mailing packaging we also, under the name SendProof PRO, offer advice and inspiration in respect of the complete (e-)fulfilment process. On the basis of the packaging scan, ‘Catch The Savings’, we help you with, for example, the optimisation of your packaging logistics process, the design of creative made-to-measure packaging and/or the development of a sustainable alternative packaging.
With the environment in mind
If you sell a lot online you need a lot of packaging material. With SendProof PRO we pay considerable attention to reducing the volume of ‘empty air’ that is mailed. We also, with the support of our research centre - The LCA Centre - look very carefully at the composition of packaging materials to ensure the environmental-impact of our mailing packaging is as low as possible.
SendProof Packaging is the proof that good mailing packaging pays dividends.
