Seems like a low starting bid for a hand-made flute.
If it really is made from a sheep femur, I suppose we could resurrect the “What IS that liquid in my whistle?” thread with some new, somewhat grosser, material. It is probably the perfect whistle for a Geico salesman.
Ye Gods! That bottom hole looks big!
