In 1991 we built a new production facility in Shenzhen, China, and by 2000 had fully transferred our plant, equipment, manufacturing technology, key production, and administrative personnel. The Shenzhen plant now covers 12,000 square meters and employs more than 450 highly trained, experienced, and skilled workers. We continually upgrade our production technology to process raw materials into finished products. Leos' offers a vast range of office supplies and accessories.
