Reijmyre was founded in Sweden in 1810 by Johan Jacob Graver. During the early 20th century, Reijmyre produced high quality cameo glass. The company changed hands many times over the years. Lennart Rosen took over in 1950, and hired designers including Johnny Mattsson, Paul Kedelv and Bert Kindaker. The Reijmyre glassworks is still in production today.
