Thank you for viewing! ^ ^ With 11 years of experience in creating breath builders, I have an original design with two holes, providing a significant load and receiving high praise from many brass bands (and music departments)! * If the load is too heavy, please use your finger to cover the hole on the right side of the mouthpiece. The acrylic pipe connecting the main body and the blowing hose is attached with acrylic adhesive, allowing for removal and cleaning, ensuring hygiene ♩ If you wish to purchase multiple items, please comment. Discounts are available ^ ^ If you purchase up to 10 at once, the price will be 10,000 yen. We are waiting for your immediate purchase, questions, and comments ♩ #BreathBuilder #BrassBand #Diet #Training
