Founded in Lille at the beginning of the century, Sepieter was originally a traditional printing house.
As time went by, the manufacture and printing of envelopes became its speciality and, as early as 1975, Sepieter established itself as the leading company in the envelope mail order business.
Today Sepieter is adapting to the new needs and offers a range of over 300 products. The company also responds, outside the catalogue, to any specific request (special sizes, positioning of windows, printing over the entire surface, ...).
