# Letterbox boxes *Since 2007, we have been the go-to wholesaler for letterbox boxes. Whether you ship flat web shop orders, printed matter or small accessories, our cardboard letterbox boxes go through the letterbox in one piece, in white, in brown and printed with your logo on request. Ordered on working days before 3:30 PM? Then your order will be shipped the same day (for items in stock).* ## **Letterbox boxes for every letterbox shipment** Letterbox mail is often cheaper to send than parcel post. With a suitable letterbox box, shipping costs therefore usually stay lower than with taller or larger [cardboard boxes](en/cardboard-boxes). Our letterbox boxes are designed for Dutch letterboxes; maximum sizes for letterbox mail abroad may differ. Because the boxes are delivered flat, they take up little space in your warehouse. Only when a shipment is ready do you fold a sturdy box in a single step. ### **How to choose the right letterbox box** **White or brown:** white gives your shipment a polished look, brown is the practical and economical choice for everyday shipping. **From A5 to A4:** choose the inner size to suit your product. There are compact boxes for small accessories, A5 and A4 formats and versions with a top flap. **E-flute cardboard:** single-wall, thin and light, yet strong enough to protect flat products. Need more volume? Take a look at our [folding boxes](en/cardboard-boxes/folding-boxes). ### **Letterbox box specifications** **Material**Cardboard, including single-wall E-flute**Colours**White and brown**Versions**A5, A4, elongated and with top flap**Sizes**From compact (180 x 115 x 27 mm) to A4 (345 x 255 x 27 mm), stated as inner dimensions**Pack size**20, 25, 50, 100 or 125 pieces, depending on the size**Printing**Available, with a white exterior**Delivery**Delivered flat### **Print your logo on letterbox boxes** Want to make a personal, premium impression?

Measure your product and choose a box with a slightly larger inner size. Also check the height: a letterbox box is flat, so the product must not be too thick. ### Can I have letterbox boxes printed? Yes, our printed letterbox boxes have a white exterior and can be printed in anything from one colour to full colour. You first receive a digital proof for approval. ### Are the boxes delivered flat? Yes, they are delivered flat and can be folded up in a single step. This saves storage space. ### Will the boxes fit through any letterbox? The boxes are designed for Dutch letterboxes. Other maximum sizes may apply for shipments abroad, so check this beforehand with your carrier. ## Producten - [White letterbox boxes E-flute - 180 x 115 x 27mm](en/cardboard-boxes/letterbox-boxes/letterbox-box-e-flute-180-x-115-x-27mm-white) - [White letterbox boxes E-flute - 220 x 155 x 27mm](en/cardboard-boxes/letterbox-boxes/letterbox-box-e-flute-220-x-155-x-27mm-white) - [White letterbox boxes E-flute - 260 x 170 x 28mm](en/cardboard-boxes/letterbox-boxes/letterbox-box-e-flute-260-x-170-x-28mm-white) - [White letterbox boxes E-flute - 310 x 215 x 27mm](en/cardboard-boxes/letterbox-boxes/letterbox-box-e-flute-310-x-215-x-27mm-white) - [White letterbox boxes E-flute - 345 x 255 x 27mm](en/cardboard-boxes/letterbox-boxes/letterbox-box-e-flute-345-x-255-x-27mm-white) - [White letterbox boxes E-flute - 350 x 230 x 28mm](en/cardboard-boxes/letterbox-boxes/letterbox-box-e-flute-350-x-230-x-28mm-white) - [Brown letterbox boxes E-flute - 180 x 115 x 27mm](en/cardboard-boxes/letterbox-boxes/letterbox-box-e-flute-180-x-115-x-27mm-brown) - [Brown letterbox boxes E-flute - 220 x 155 x 27mm](en/cardboard-boxes/letterbox-boxes/letterbox-box-e-flute-220-x-155-x-27mm-brown) - [A5 - Mailbox boxes 255mm x 160mm x 27mm - Brown](en/cardboard-boxes/letterbox-boxes/mailing-box-a5) - [A4 Letterbox Boxes 299mm x 213mm x 27mm - brown - 100 pieces](letterbox-box) - [Brown letterbox boxes E-flute - 310 x 215 x 27mm](en/cardboard-boxes/letterbox-boxes/letterbox-box-e-flute-310-x-215-x-27mm-brown) - [Brown letterbox boxes E-flute - 345 x 255 x 27mm](en/cardboard-boxes/letterbox-boxes/letterbox-box-e-flute-345-x-255-x-27mm-brown) --- Source: https://www.kortpack.nl
