What are letterbox boxes?
Designed to make transporting your items safely through the post to their destination even easier, letterbox boxes do exactly what they suggest - they fit through letterboxes! Available in a variety of sizes, letter box boxes keep your goods safe and secure with the addition of a lock whilst in transit. Peace of mind for you, and the recipient.
What’s the difference between a letterbox box and a postal box?
Postal boxes are a more standard parcel shape, whereas letterbox boxes are designed to fit through the doors of recipients - no waiting in required! Not only this, but with optional locks available on letterbox boxes, you get extra peace of mind when it comes to security during transit.
