The company was started by two twin brothers, Arne and Rune Ottosson. In 1984, Arne left because the company could not handle two people and chose to seek support elsewhere. Arne has, however, continued to help his brother, but the stamping is after 1984 without an initial A. They both apprenticed with Erik Fransson at the firm Konst-Tenn in Älmhult. Erik Fransson's Konst-Tenn was a nursery school for several famous tinsmiths.

The Ottosson brothers have mostly worked with jewelry, but a number of other objects appear.
