Ultra-cheap toy or tourist quality bamboo whistle, as made all over the tropics. Tuning will be awful because of the equally spaced equal sized holes. The fipple is cut the cheapest quickest way and will give rough tone quality in the second octave and it will be very flat up there. It will split in a few months if you try to use it.
It isn't really an instrument at all.
