    Information

    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.

    Benefits of letterbox-friendly boxes

    As a box small enough to fit through a letterbox, and big enough to fit a range of different items inside it, there are so many benefits that come with this type of packaging, including:
    • Royal Mail compliant – our letterbox boxes meet Royal Mail’s postage size specifications meaning you can send your item safely with Royal Mail.
    • Safety – if you’re sending a more fragile or important item, it is much safer sending in a postal letterbox box than it is in a regular envelope whilst still being able to fit through the letterbox.
    • Efficiency – our letterbox boxes are designed to be completely efficient, using minimal material to reduce waste and cut down on packaging expenses.
    • Customer experience – letterbox boxes offer a great customer experience with their easy openings and convenient size that means they can be delivered directly through the letterbox without the recipient needing to be home.
    • Eco-conscious – letterbox-friendly boxes are 100% recyclable making them kinder on the environment.
    • Elegant presentation – there’s something elegant about packaging that can easily fit through your letterbox. Our letterbox boxes are therefore perfect for presents, vouchers, or special notes.
    • Customisable – our letterbox boxes are fully printable, meaning you can add your business’ logo and branding whether you’re a small start-up or large corporation.

    What are postal letterbox boxes used for?

    Postal letterbox boxes are extremely versatile and can fit a range of different items in them. Here are just a small number of ways letterbox-friendly boxes can be used, but the possibilities are endless.

    Small products

    Letterbox boxes are the perfect size and shape to ship small products for a range of industries. It’s a secure, convenient, and cost-effective method for delivery which is perfect for small businesses such as Etsy shops and other home businesses. They’re great for items like skincare and makeup, jewellery, and tech accessories.

    Welcome packs

    Welcome packs are a great way to show your customers or employees your appreciation, and can help them feel more engaged with the business. Letterbox boxes are a practical way to send welcome packs or thank you gifts in a visually appealing and convenient way. They can hold items like snacks, office supplies, and more whilst representing the business through bespoke branding.

    Online retail

    Letterbox-friendly boxes are a game changer for online retailers. They’re great for streamlining shipping processes and reducing delivery costs whilst maintaining customer satisfaction with convenient letterbox delivery. 

    Letterbox boxes for safe delivery

    We specialise in ecommerce letterbox boxes, ideal for businesses that sell their goods online, such as eBay, Etsy, and Vinted, and want a safe and secure way of dispatching them to their new homes. Our postal letterbox boxes also act perfectly as subscription gift boxes.

    Our large cardboard letter box boxes suit a variety of items due to the range of sizes available. However, naturally they are most applicable to smaller items that can be packed relatively flat, so that they can fit through letter boxes as intended.

    Available letterbox box sizes

    Although all of our letterbox boxes are Royal Mail compliant and can fit through a standard letterbox, they come in a range of sizes depending on what you specifically need them for. Our boxes are delivered flat packed, making them easy to store for as and when you need them. They are also super easy to assemble – all you need to do is use the pre-folded lines as a guide.
