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 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.
These A4-size mailbox boxes are supplied flat and are very easy to assemble. Insert a book, CD, clothing or other small products into the box, close the box using the closure flaps and your package is ready to go and will arrive neatly and securely in your customer’s mailbox.
Available in white, green, red, pink, black and orange. Also available in A5 size.

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.
