The Biella brand was established in 1923 from the stationery and paper goods factory founded in Biel in 1900. In 1908, it produced its first binder, the predecessor of the later Bundesordner, which remains a flagship product and synonymous with Swiss orderliness today. In addition, Biella produces numerous other products that facilitate organization and clarity in school or work life. The company is one of the leading office supplies manufacturers in Europe, not least because it keeps pace with the times and successfully balances the still significant importance of paper documents with the increasing digitization. Today, Biella employs around 200 staff and is headquartered in Brügg, Bern. The company focuses on ecological, economic, and social sustainability and produces from certified raw materials. Furthermore, it places great importance on promoting both its workforce and the environmental compatibility of its products.
