Here are three mouthpieces that I no longer use, along with the replacement of my instrument. There are no boxes for any of them, so I will wrap them in bubble wrap for shipping. No individual sales. To prevent any problems, please take a close look at the photos before purchasing. Please refrain from purchasing if you are a nervous person or a clean freak, as these mouthpieces have been handled by people. I cannot answer questions about the exact period of use, as I do not know. Model Numbers: DENIS WICK 4AL GP finish (large shank) Condition: There are scratches on the shank from use. DENIS WICK 4AY (small shank) Condition: There are areas where the plating is thin and dirty from use. DENIS WICK SM4M (medium-small shank) Condition: There is dirt on the shank. Surface finish is unknown.
