Mailbox box 345x255x28mm - A4+ brown

This brown A4+ letterbox box measuring 345 x 255 x 28 mm is a cardboard shipping box for larger flat products that can be delivered through a letterbox. This letterbox packaging is suitable for shipping documents, printed materials, clothing, accessories and other relatively flat products. With a suitable letterbox shipment, the recipient does not need to be at home to personally accept the parcel.

The letterbox box is made from single-wall corrugated cardboard. The corrugated cardboard provides strength and helps protect the contents during handling, transport and delivery. The brown finish gives the packaging a neutral appearance suitable for a wide range of products.

Thanks to its top-loading construction, the box can be opened widely from the top, allowing products to be easily placed inside. The A4+ format of 345 x 255 mm provides more space than a standard A4 letterbox box, while the height remains limited to 28 mm.

For webshops and businesses shipping larger flat products, this brown A4+ letterbox box is a compact shipping solution that combines protection with the convenience of letterbox delivery.
