You'll put down a nominal refundable deposit and have to pay return shipping.I think we had 20 flutes flow through our house before she bought the last one.
My daughter plays open hole, but I don't know why or what her views are.
I believe you can buy plastic plugs for open hole flutes - so if you buy open hole and wish to play it as closed, you can insert the plugs.
So you might want to check out if any of them are being held that you can get to.
She had played some really pricey ($15K ) flutes that she says are a dream, and others that she doesn't like as much as hers.
The practical value is small, the additional opportunity for off notes is large. I might just get in touch with instrument manufacturers.
