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.
We also stock mailing bags as another packing option that can result in a saving of costs when sending items such as clothing.
If your package falls outside of the large letter postal box size we do offer a full range of small parcel boxes and cardboard boxes suitable for shipping large and heavy goods.
We specialise in producing custom cardboard boxes specifically designed for your requirements. Get in touch to let us know what you need.
If you’re looking to take your packaging to the next level we offer both full colour and single colour box printing. We can print all of the above letter postal box sizes in black ink.
Postal box sizes marked with √ can be colour printed.

Karl WorthingtonGreat service! Only took 5 days for delivery of a couple of custom made boxes. Boxes are good quality and strong (double walled). Not the cheapest and delivery cost is on the higher side but this company is one of only a few places that accepts small orders so I would use again.
