I've got 8 pairs of P1 props that came with my recently purchased Phantoms. The hang tags don't come with the props that are shipped with the Phantom but they are the same props. 100% genuine DJI. $15 for 2 pair shipped to USA only. See Amazon's price for comparison. http://www.amazon.com/gp/offer-listing/ ... dition=new These are self-tightening with the black and silver nuts, CW and CCW.
