This is a Shannon D flute in delrin made by Walt Sweet. This is a very well regarded non-wooden flute; low to no maintenance, and very durable. It plays very well. The flute is in very good condition. I am the second owner, and it is in the same condition in which I received it. I attempted to show the only "defects", if you want to cal them that. There are some small small surface micro scratches that are visible with the right lighting.
