This is an adjustable blowstick with mouthpiece. The main advantage of this system is that the blowstick is on a ball -joint which means you can adjust the angle of the blowstick to suit your needs. It will then remain fixed in place with no chance of it springing out of your mouth when competing. There is a built in valve in the bottom of the blowstick and it comes with an adjustable length mouthpiece, so it can be made to suit any size or age of player. The standard mouthpiece is round however, there is a spare one included which is oval - for those that prefer the oval shaped mouthpiece for blowing into. A brilliant product.
