Royal Mail Large Letter Parcel Boxes

Large Letter Boxes

Large letter postal boxes (also known as Royal Mail PIP boxes) are a great way of packaging products in both a secure and elegant way. Ideal for e commerce, large letter postal boxes can give your customers a quality branded experience as the first impression of your company they receive.

Large letter postal boxes unique design means they assemble without the use of tape or glue but still remain robust enough for use as packaging for fragile items. Postal boxes offer a plastic free packaging option, an increasingly important consideration when keeping your business environmentally-friendly.

And let’s not forget – the slim and lightweight design of these boxes will save you postage costs as the shipping charges fall into the Royal Mail PIP large letters category rather than the small parcel.
