Yamaha cases are precisely molded to each instrument to provide a snug fit and prevent jarring. This case is specifically for the YSH-301/411 Sousaphone, although other models may fit. The case is made from durable molded plastic. Our cases use riveted metal hinges and latches, which are very durable and easy to operate. They are much less prone to breakage compared to our competitor's molded hinges and latches.
