This fan was made by Lostris. It is not a complete folding fan, & takes a full round to open if it is put in a “closed” position. It is more natural for it to stay splaid out, “open” as it were.
This fan doubles as a pan flute & when playing the right melodies, mystic effects can come from it. There are 13 notes on this, but they are not in the standard pentatonic scale that is frequent in the jungle lands where this was purchased. It has the notes of Lostris’s homeland.
