The Protec N265/RX mouthpiece case provides secure storage for 3 trombone or alto saxophone mouthpieces. High-quality, water-repellent neoprene has been used for the outer material. The mouthpiece case is secured with a zip, preventing the mouthpieces from falling out. An adjustable belt loop is fitted to the back, which can be individually adjusted using a strong Velcro fastener.
