Meyer Alto Saxophone Mouthpiece Tip opening: 6 Medium facing, medium chamber. There are scratches on the outer baffle and white stains inside, as if calcified. The tip and table are clean, but please understand that there are some scratches and stains as mentioned above. Originally, I received it from someone who said it was used by a professional in the past, and I was grateful to have it. It has been in this condition since then. I thought it might not be good to clean it too much, so I left it as it was. I would like to leave the cleaning to the person who purchases it. It plays well!
