These sturdy corrugated flat postal boxes are ideal for shipping thick catalogues, books or photo albums. Both available sizes (A4 and A5) of the cardboard postal boxes will fit through the slot of a standard letterbox; the resulting affordable postage rates make these boxes a highly attractive option.

For a small surcharge, we can also offer custom printing on your post boxes. View the custom-printing possibilities here.
