This is a Vandoren BD5 Bb clarinet mouthpiece. I purchased this a few years ago, selected by Akihisa Kato, and used it for about six months. I kept it as a backup for a while, but I'm selling it now that I've switched to the BD5HD. The marking on the bottom is ○. There are no noticeable scratches on the tip rail, but the logo is faded and there are signs of use, such as marks from the ligature. Please refrain from purchasing if you are concerned about this. It will be sent in its original box. Please negotiate the price in the comments.
