Store and ship with confidence - 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: 375mm x 375mm x 100mm
  • Board Grade: 200W
  • Flute: E Flute
  • Made from 63% recycled cardboard
  • Flat packed — easy fold assembly, no tools required
  • Brown kraft finish

A versatile square postal box suited to a wide range of items - gifts, homeware, candles, ceramics, clothing, electronics and more. The equal length and width make it a practical choice for squarish items that don't fit neatly into a standard rectangular box.

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 straight out of the box.

Board construction: This box is made from 200W Grade E Flute board. E Flute is a fine, tightly-spaced corrugation that gives the board a smooth surface and a neat finish. 200W is a stronger variant of the standard 200 grade - it offers better resistance to moisture and compression, making it a more robust choice for heavier or more valuable contents.
