Brown mailboxes are made of strong corrugated cardboard and ensure a strong and durable mailbox for shipping. Our mailing boxes are manufactured locally in Denmark and contain up to 70% recycled cardboard. We also have brown mailing boxes in a variant where the mailbox is slightly lighter brown and made of 100% recycled cardboard. The only print you will find on the brown mailboxes is a small, black FSC logo on the bottom of the mailbox so your customers can see that you are sending in an environmentally sound manner. The brown mailboxes also come in many sizes, so you can find both mailing boxes that can be sent with various freight companies.
