Brown Postal Box A3 B-flute - 430mm x 300mm x 120mm

Brown postal box A3 430 x 300 x 120 mm – for wide and flat items

Since 2007, we have been the go-to wholesaler for A3 postal boxes. This size is made for shipments that are mainly wide and flat, not for products that need a lot of height. The inner size of 430 x 300 x 120 mm is slightly larger than an A3 sheet of 420 x 297 mm, so drawings, posters and documents, for example, lie flat in the box. It is made of B-flute corrugated board and comes with the lid already attached.

Assembling and closing

The postal box is delivered flat and can be assembled by hand without tools. The lid is already part of the box, so there are no loose parts. After packing, you close the box with packing tape. That way each pack takes up little storage space.

Who is this size for?

This postal box suits A3 documents, portfolios, art prints, calendars or clothing laid flat. The stated dimensions are internal dimensions, so you can easily see whether your product, with packing material if needed, fits in the box. If your shipment is thinner than this, take a look at our letterbox boxes. If your product needs more height, you will find a wide choice of folding boxes, or browse all cardboard boxes from Kortpack.

Advantages of this A3 postal box

• A3 flat: an A3 sheet fits without bending or folding.
