In 2005, the Sprouse brothers joined Dualstar Entertainment to produce "Sprouse Bros" products for preteens (9 to 12 year olds) and teenagers. The Sprouse Bros brand has a clothing line, a comics series, and a magazine. In 2006 Dualstar and Leisure Publishing LLC started a magazine called "Sprouse Bros. Code" for boys. In 2007 Simon & Schuster Inc. published the two volumes of a book series named "Sprouse Bros. 47 R.O.N.I.N.", about two young spies. In 2008, the brothers ended their association with Dualstar. They continued their clothing line which is 'on hold'. The things in their clothing lines are only sold online.
