From just 100 pieces

Paardekooper is the address for ordering printed letterbox boxes in small quantities.

We supply the mailing boxes in quantities of 100, 200, 300, 500, 1,000 or 2,500 pieces per design at very keen prices. You can, of course, order larger quantities on request. Our inexpensive, printed letterbox boxes are high-quality, ordering them is very simple and, thanks to the short delivery time, just five working days after you approve the print proof you will have your printed letterbox boxes in house.

Two sizes

Our SendProof letterbox boxes are made of sturdy cardboard and are white on the outside.

They are available in two sizes: A5 and A4. Your own, full-colour printing will be on the top of the box in an area that is 200 mm wide by 131 mm high for the A5 boxes and 200 mm wide by 211 mm high for the A4 boxes (see the specifications for preparing/supplying your own design further down this page). The content of your printed design is entirely up to you. How will you surprise your customers?
