COS was founded in 1977 by Dominique Lyone, whose family fled from Egypt to Australia after the 1967 six day war. Following in his fathers footsteps, he started a local office stationery business with two staff in Western Sydney. In those early days the top selling item was a typewriter ribbon.
Over 40 years later, COS has over 500 staff delivering thousands of products to businesses across Australia. With warehouses in every state, COS is still owned and managed by Dominique, and is now joined by daughters Belinda and Amie who hold key executive roles.
