The Brown C4 Maltese Cross Royal Mail Large Letter Box is a lightweight single wall postal carton designed to make near-maximum use of the Royal Mail Large Letter dimensional allowance. With internal dimensions of approximately 337 x 236 x 19mm and external dimensions of approximately 349 x 249 x 24mm, it provides a large, low-depth mailing format for A4 documents, tablets, accessories, printed material and other slim ecommerce products.
Its Maltese Cross quick-pack design is made for operational efficiency. Simply place the item in the centre, fold the surrounding panels over and secure the carton with tape. This makes it particularly suitable for ecommerce businesses and fulfilment operations packing larger volumes of postal orders.
The brown kraft construction provides a practical economy alternative to the more presentational White C4 PIP carton while still providing rigid cardboard protection for products travelling through the postal network.
