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 inhale 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. A guide with detailed instructions is included. This upgraded model: Has fewer parts than the previous model, making it easier to clean, so you can use it cleanly and safely. As shown in the second photo, each part can be disassembled, making it easy to wash and disinfect. The breathing pipe can be cleaned with a thin brush or a foamy kitchen detergent that doesn't require scrubbing, so you can keep it clean. The ping pong balls have been upgraded to colorful ones as shown in the third photo! If in stock, we can 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.) Bulk orders are welcome! For bulk orders, the price per piece will be lower.
