This is a classic, traditional #7 mouthpiece. I purchased it around 2018-2019 and used it for about a year. However, I've been primarily using other mouthpieces recently, so I've kept this one as a backup for a long time. It's been crafted with great precision and, as its reputation suggests, it's a mouthpiece that produces a beautiful sound. Currently, it's difficult to obtain, so please consider it if you're looking for one. Thank you for looking.
