Interlocking White Postal Boxes

These excellent quality presentational boxes are die-cut white postal boxes made with fold over ends and earlock lids. They are designed to fit items that will go as a ‘large letter’ with royal mail, saving on postage costs and ensuring the item stays in one piece in a secure box, and does not move out of proportion. These PIP royal mail large letter boxes are available from stock and are a great solution for businesses looking to save money on postage, while offering a good presentable solution to their customers. The C6 size is also made specific for mobile phones and accessories. The C4 size is a maximum size large letter box – giving maximum dimensions allowed under the royal mail regulations for an item to be sent as a large letter.
