The Malvern, Worcestershire-based company hand finishes envelopes to produce short run bespoke sizes.

Pendragon has now introduced Enduro paper in its range, a tri-laminate sheet which incorporates a layer of polythene sandwiched between two paper substrates, giving it added strength as well as a high standard of print.

George Silverman, envelope guru at Pendragon, said: "Although Enduro has been around for a while, it's a German product, it has not been offered for bespoke products before."

The company produces envelopes in bespoke sizes and shapes on a made to order basis. It predominantly works with trade printers, however Silverman said the company would "not turn down" work from elsewhere.

Although traditionally a packaging manufacturer, Pendragon employed a number of ex-staff of Ledbury-based envelope manufacturer John Dickinson in 2008.
