I have just acquired a set of bamboo, and bone flutes, (one possibly made from an antler)...

I am informed that they are called "de"s or "di"s.

they have the same fingering as whistles and there is a hole just below the mouth hole which can be covered with bamboo paper to make a "musical mosquito" (kazoo)type noise.

does anyone know anything about maintaining them?
