Corbie brothers After years of always working for a boss and having been able to gain a lot of experience and the necessary courses, the brothers had enough capacities to start their own trading company. The brothers Dirk and Cornelis Corbie have a good partnership. Both went back to study to obtain the necessary qualifications needed for this venture. This makes their slogan 'Corbie Brothers Strong in all your craftsmanship' a truth that can be guaranteed.
