Metal saxophone mouthpiece made by D.C. Studio, featuring a unique cut shape. - Model name: Dave Guardala Studio Thank you for viewing. There are no tooth marks because a patch was used. The rails are very well made, thin, and easy to play. A patch is attached, so if you are concerned, I will remove it before shipping. Please let me know your request in the comments.
