Beautiful, strong and LIGHT! Despite the very small size, this case will take up to three soprano instruments as well as plenty of storage. Even if only used for the bass clarinet, the case is tiny - half the volume of a bass clarinet case supplied with new instruments. This case is roughly only one-third of the volume of the alternative volume of cases for carrying a bass and two/three sopranos. The instrument joints are all suspended in the air with no keywork being touched. All blocking is Velcro-mounted and adjustable. The walls of the case are completely rigid and will not flex.
