Viola tailpiece. Made of rosewood, compatible with 16-inch to 16.5-inch violas. The metal fitting that supports the strings is the type that secures them by tension, so they may come off easily. Therefore, I will secure it with masking tape before shipping. (This is not a defective product) The tail cord is rope-style, and I removed it as is from a previous use, so the length can be used as is. I plan to ship via Yu-Packet Post.
