What is MB (Marcus Bonna)? Marcus Bonna, founder of MB (Marcus Bonna), was a horn player with the Sao Paulo Symphony Orchestra from 1982 to 2002. Bona was fed up with the weight of her horn case, which was always a hassle when traveling during her daily performances. With this in mind, she wanted to create a way to transport the horn more easily and safely, and to free more people from unnecessary worries about playing the horn, an instrument she loves, so in 1991 she came up with her first original horn case, which was light, compact, and had an innovative design. The fiberglass cases designed by Bona far exceeded his expectations and were well-received by orchestra members, quickly spreading throughout the orchestra. This marked the beginning of MB cases. When the Munich Philharmonic Orchestra performed in São Paulo in 1991, the horn players showed great interest in Bona's cases. This led to orders not only from within Brazil but also from overseas, and in order to spread these cases to horn players around the world, Mr. Bona founded MB, a company named after himself. Today, MB not only manufactures horn cases, but also a variety of other cases for trumpets, trombones, clarinets, oboes, bassoons, etc. Each and every one of these handcrafted wind instrument cases is loved by musicians around the world, and MB has established itself as a leading brand of wind instrument cases. The MB case is characterized by its light weight, robustness, and compactness. Every case is meticulously handcrafted, boasting a beautiful finish and stylish design. A wide variety of colors are available, allowing you to customize your own unique case. All products come with backpack-style or shoulder-style straps for easy portability (the type and number of included straps vary depending on the model), as well as cushions to protect the instrument, thoroughly eliminating any stress the player may experience. MB Cases, which prioritize reducing the player's mental burden, are good news for wind instrument players worldwide who struggle with the hassle of carrying heavy cases.Weight / 3.2kg Size: Vertical / 220mm Width / 550mm Depth: 200mm *Weight and size are approximate values.
