Self-locking mailing boxes with a hinged lid — designed for e-commerce, retail, and subscription businesses that need fast, professional packaging without tape. The hinged lid folds open for easy loading and clicks shut securely, keeping contents protected through the postal and courier network.
How They Work
No tape, no glue, no tools. The die-cut design folds into shape in seconds with a hinged lid that opens and closes cleanly — ideal for high-volume packing environments where speed matters. Delivered flat-packed for efficient storage.
A Note on Sizing
These boxes are made from lightweight 2mm corrugated cardboard. The hinged lid design adds rigidity, but as sizes get larger, please consider the total weight and fragility of your contents before purchasing. For heavier or fragile items, consider stepping up to one of our heavier-duty shipping boxes or adding internal padding.
Available Range
Available in white and recycled brown across a wide range of sizes — from small cosmetic and jewellery mailers through to A3 and A4 formats for books, documents, and retail products. Mug and coaster-specific sizes also available. Custom printing available on larger orders.
