Our family links to professional cleaning and restoration go back to 1832. Since1987 we have specialized in the manufacture of unique cleaning, restoration and preservation polishes for precious and semi-precious metals.

Outside the EU countries, we sell exclusive licenses to companies to manufacture and sell Holland Hallmark products, within a specified territory. The manufacture is based upon a well proven and simple production system. The demonstration and training facilities are based in Holland, where licensees are given detailed manufacturing instructions as part of the license support.
