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 other musical groups)! * If the load is too heavy, please cover the hole on the right side of the mouthpiece with your finger. The acrylic pipe connecting the main body and the blowing hose is attached with acrylic adhesive, allowing for the hose to be removed and cleaned, ensuring hygiene! If you wish to purchase multiple items, please refer to the following: * For single item sales, we are selling at a discounted price of 715 yen (originally 1299 yen) for those who want to try it out. However, the unit price for bulk purchases of 2 to 9 items is set from 893 yen to 898 yen. (For purchases of 2 or 3 items, shipping is 455 yen via Yu-Packet Plus, but for purchases of 4 to 10 items, shipping is 750 yen via Rakuraku Mercari Delivery, size 60). If you purchase a maximum of 10 items at once, the price will be 10,000 yen (unit price 825 yen). We are waiting for your immediate purchase, questions, and comments! #BreathBuilder #BrassBand #Diet #Training
