Hilitand Trumpet Mouthpiece for Beginners, Silver-Plated Brass, Practice Mouthpiece for Trumpet

---------------------------------------------------------------------- The entire piece is made of copper, and the surface is silver-plated to enhance corrosion resistance. By pulling it down and fixing the shape of the mouth, it increases the endurance of the oral muscles, strengthens the biting force of the lips, and improves the concentration of the lip muscles. The force applied when gripping is the opposite of the force during normal training (reaction force). This helps to alleviate necrosis of the orbicularis oris muscle caused by overtraining every 20 seconds and improves the endurance of the orbicularis oris muscle. The rubber band is removable and can be attached and detached. It increases friction in the mouth muscles and has a smooth surface when gripped by hand, making it less likely to fall off. Superior polishing treatment is applied to the surface of the object, giving it a glossy finish and enhancing its overall aesthetic appeal. Contents: Mouthpiece x 1
