Marcus Bonna was a São Paulo State Symphony Orchestra horn player from 1982 to 2002.
After suffering an accident in 1990 and have had his back seriously hurt, he projected a case for himself, lighter, compact and with a brand new design in order to facilitate the transportation of his instrument, as the cases which there were in the market were too big and heavy.
At his surprise, the case was so successfully among his colleagues from the orchestra that, in a short time, the same colleagues had the new case made in fiberglass by Marcus Bonna himself. (Model MB 1).
In 1991, the Munich Philharmonic Orchestra had a performance in São Paulo. When the horn players from this orchestra saw the new horn case model they got very impressed and interested in getting one.
For this reason, to start sending the orders, not only to Brazil but also abroad, in 1991 the MB company was founded, that nowadays has 81 employees at his own head office located in Bragança Paulista (80km from São Paulo).
Besides the production section and the management section, the Company also has a good canteen, play room and an auditorium with a grand piano to classes and chamber music.
The MB exports about 700 cases a month for more than 25 countries. All the cases and mutes are handmade and most recently launched a new product line: wine bottle case (wine.mbcases.com).
The cases model are exclusive (some of them are protected by a patent), all designed and developed by Marcus Bonna himself.
