I bought this at a used shop a little while ago. Personally, it feels like an M30, a mouthpiece that has a compact and pleasant sound, yet still has enough resonance. (It feels like it resonates significantly more than the M30s I've handled in the past.) I've played it a few times. I'm selling it because I found a perfect mouthpiece after getting this one. The Vandoren engraving is slightly worn, but it has a serial number and is still relatively new. I will put it in a box for a different Vandoren mouthpiece model and pack it carefully to send via Takkyubin Compact. I think it's better not to remove the patch (it was on there when I bought it), so I'll send it as is. It will probably get dirty, but please let me know if you absolutely want it removed. I don't think it's worth that little, so I'm not considering a price reduction below this in principle. If it's only a small amount, I'm more likely to respond to price negotiations on the app than in the comments.
