# 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.
