In this model, the rod is kept in a sleeve fixed to the lid that, in addition to protecting it, prevents it from damaging the bell of the instrument. -Increase the interior capacity to transport the largest number of accessories, for which two compartments have been designed inside and an area in which two nozzles can be located. -Enable that optionally can be attached to the case covers for the transport of costumes, laptops, music stands or mutes.
