These Postal Boxes are designed with postal-approved strength and security, so you can trust that your packages will arrive safe and sound.

Specifications:

  • Size: 340mm x 300mm x 35mm
  • Board Grade: 200N
  • Flute: E Flute
  • Made from 63% recycled cardboard
  • Flat packed - easy fold assembly, no tools required
  • Brown kraft finish

A slim, flat postal box ideal for sending documents, prints, photographs, artwork, books, clothing and other low-profile items that need protection without bulk. The shallow depth keeps postage costs down while still giving the contents a rigid, crush-resistant shell.

Made from 63% recycled cardboard, supplied flat packed and quick to assemble - just fold and seal, no tools required. The brown kraft finish gives a clean, professional appearance.

Board construction: This box is made from 200N Grade E Flute board. E Flute is a fine, tightly-spaced corrugation that gives the board a smooth surface and a neat finish — ideal for lighter items where presentation matters. 200N is a standard single wall grade, well suited to everyday postal use for lighter contents.
