- Wi&Fi Mouthpiece - B♭ Clarinet - Z3 Thank you for viewing. I purchased this in early January 2026, but I preferred the S series I bought around the same time, so I'm selling this as I haven't played it much recently. I will thoroughly clean it with a mouthpiece cleaner and send it in the included bag and box. I used mouthpiece patches to prevent teeth marks, but I will remove them if you don't need them, so please let me know. I haven't played it much, so I don't see any noticeable scratches, but please understand that this is a used item and is viewed from a layman's perspective. No claims and no returns, please. Z Series: Uses a Zinner bore. It has a natural resistance and a sweet, warm tone. Similar opening models from other companies: Vandoren BD5 and Playnick B2, etc.
