This is a lightweight case for euphonium made by MB Cases in Brazil. This case should fit most instruments up to 68cm in length and 32cm bell. The shell in the bottom of the case is a fiberglass tray, while the lid is made of firm padded fabric, similar to carpet padding. This reduces the weight significantly from the Bonna all-fiberglass case. Choose this case for local travel by car, train or bicycle, and choose the heavier version for air travel.
