As its name suggests, DE MAN - WERKENDAM was founded in Dordrecht in 1942. After starting out as a stamp wholesaler, album production was launched a few years later. Until the late 60s, production was entirely in-house. With the move to Werkendam, production was also outsourced. In 1995, we took over the HARTBERGER brand and transferred the production of coin holders to Werkendam. In 2005, the production of binders and sheets was added. We also produce ring binders and sheets of all shapes and sizes in a separate company for other companies. If you are interested, please visit our special website
