Royal Mail Large Letter Cardboard Boxes
Our Royal Mail postal boxes are specifically designed to fit through standard letterboxes, making them perfect for the Royal Mail's Large Letter service. These boxes are crafted from single-wall corrugated paper, which offers superior protection compared to plastic mailing bags, ensuring that important documents and similar items are securely shielded during transit. Utilising the Large Letter option is one of Royal Mail's most cost-effective courier services, helping you keep shipping costs down. Additionally, our postal boxes are not only biodegradable but also compostable, aligning with eco-friendly practices by helping to reduce waste and promote sustainability in packaging.
Suitable for Royal Mail
When selecting boxes and packaging, it's crucial to choose options that meet the specific requirements of the service you're using. Royal Mail has strict guidelines on what qualifies as a Large Letter, so using the right size boxes is essential to avoid any unexpected charges for oversized items. Our cardboard boxes are designed to adhere to these dimensions, ensuring you won't face additional fees. They are also affordable, making them a cost-effective choice for your mailing needs. Plus, they come in plain brown cardboard, which can be easily customised with stickers or stamps to add your branding, providing a professional look while keeping costs low.
