This product is for you if you play a wind instrument. It's a great product used by many brass bands! It's attracting attention as a breath training method you can do at home. Just by doing this training, you'll naturally be able to take deep breaths and exhale deeply, and the tone of your instrument or voice will change. How to use it: Simply breathe in and out through the tube, and keep the ping pong ball inside floating. It takes some practice, but with practice, you'll be able to breathe in deeply and exhale deeply. It's most effective if you do it before playing your instrument, but it's also effective if you do it at home when you can't practice. There are three holes other than the mouthpiece, so you can change the training load. A guide with detailed instructions is included. This upgraded model has been made cleaner and safer by reducing the number of parts compared to the previous model, making it easier to clean. As shown in the second photo, each part can be disassembled, making it easy to clean and disinfect. The breathing pipe can be cleaned with a thin brush or a foam-type dish soap that doesn't require scrubbing, so you can keep it clean. Parts other than the ping pong balls are made in Japan. The ping pong balls are also all new and shipped after being washed. As shown in the third photo, we've upgraded to colorful ping pong balls! If we have them in stock, we can also accept color requests for the ping pong balls. (The first photo shows a pink ping pong ball, but the color will be random if you don't specify.)
