Delrin keyless flute

Here is a polymer/delrin flute in D. I didn't make this one but I did some work on it to improve the quality of the sound. The advantages of these polymer flutes is that they require almost no maintenance. Well, every instrument needs a clean now and again but no need for oiling this. The size of the embouchure hole and note holes means that it doesn't take a lot of air to fill and the holes are easy to cover too.
