Custom flat postal boxes

The flat postal boxes are made from white or Havana robust corrugated cardboard. You can use them to ship products like books, CDs and items of clothing securely and in style. The flat boxes are resistant and fully customisable: you can print your artwork on both the outside and the inside. There are three sizes available: A5 (21.6x15.6x3 cm), A4 (30.6x21.6x3 cm) and A3 (42.6x30.6x3 cm). Select your preferred customisation options and create your ideal flat postal boxes.
