Stamp manufacturing since 1932
Stempel-Wolf GmbH is a long-established stamp manufacturer based in Siegen (North Rhine-Westphalia) with over 90 years of experience in stamp production. The product range includes company stamps, office stamps, wooden stamps, date stamps, number stamps, electric stamps, all-round stamps and special stamps, as well as stamp pads, stamp inks and accessories. The stamp plates are engraved and cut by laser from vulcanized natural rubber using the computer-to-plate process; assembly onto stamp bodies with beechwood handles from local forests is done by hand. Customers include private individuals and schools as well as trades, industry, retail, administration and freelancers; the customer list includes Allianz, BMW, IKEA, Metro and Porsche, among others. Orders are possible with no minimum quantity, with a delivery time of 1–3 days via the certified online shop or directly at the specialist store at Wallhausenstraße 55. More than two thirds of the stamps are produced in a climate-neutral manner; an in-house stamp museum displays around 200 exhibits on the company's history.
