The Brazilian Marcus Bonna and his wife have dedicated themselves to the production of highly functional cases. All their cases are designed to meet the highest standards of workmanship and optimum practical use. Due to the floating bearing there is no contact with the instrument mechanics. The inner material is made of soft foam and covered with nylon velvet.
