This is a Yanagisawa metal mouthpiece, size 6, for alto saxophone. I am selling it because I don't use it very often. It has some signs of use, but I think it's in good condition. For a short time, I played it without a mouthpiece patch (about 3 or 4 times), so there are a few slight teeth marks. If you have any questions about specific areas, please leave a comment and I will add more photos. To prevent deformation during shipping, I will ship it with a spare reed attached. Please discard the reed upon arrival.
