In Stock Letterbox Friendly Postal Boxes

Our in stock letterbox friendly range is designed to fit through a standard UK letterbox, meaning your customers don't need to be home to receive their order. Every size is dispatched within 1-2 working days straight from stock, no waiting on made-to-order lead times.

Nearly every box in this range is built to Royal Mail's large letter tariff (25mm depth or under), giving you the cheapest possible postage. The one exception is our 210 x 110 x 35mm size, which is slightly deeper to accommodate bulkier items like mobile phones, so it ships on Royal Mail's small parcel tariff instead, but it's still slim enough to fit through most standard letterboxes.

Manufactured from FSC® certified brown kraft corrugated cardboard and completely plastic free, every box in this range offers a reliable, sustainable packaging solution without compromising on protection or presentation.
