Founded in 1918 as a mail-order business, Clas Ohlson AB has evolved into one of the largest home improvement and specialty retail chains in the Nordic region. The company's product portfolio is divided into five main categories: hardware, electrical, multimedia, home, and leisure. It offers a wide range of items including DIY tools, smart home electronics, cleaning supplies, and spare parts. Clas Ohlson sells products under its own proprietary brands—such as Cocraft, Cotech, and Coline—as well as established third-party labels. Geographically, the company's core markets are Sweden, Norway, and Finland, where it serves both private consumers and small businesses. In recent years, Clas Ohlson has expanded its digital presence and acquired companies like Spares Group to strengthen its offering in electronics accessories and spare parts.
