Viola Tailpiece This tailpiece is from when I purchased the instrument, so there is no product description. Only A has adjusters. I was told the material might be ebony. It produces a soft, viola-like tone. Used for 2-3 years, then stored at home. There is no original box, so it will be placed in a simple container and wrapped with cushioning material for shipping. It will be delivered to your mailbox. I am a beginner, so I don't know the details. Please understand that this is a used item. Please refrain from purchasing if you are overly concerned about details. Thank you for your understanding.
