Flat Postal Boxes
Flat postal boxes offer a sturdier alternative to plastic postage bags, making them more suited to shipping delicate paper or electrical items such as books and DVDs. Made from puncture-resistant, single wall corrugated cardboard with a Kraft paper finish, our range of large letter postal boxes are ideal for ensuring items are protected throughout the shipping process and arrive in perfect condition.
Our flat postal boxes are incredibly convenient as they’re easy to assemble and require no glue or tape to hold them together. Plus, they feature a cut-away hole which makes them easy to open and close. They’re available in a wide range of sizes, from smaller boxes which are ideal for jewellery or gifts, to large letter postal boxes which are best suited to documents.
