I bought a 3 pack of flat knocks and they wont work with my xbow. they run about 24 bucks for a 3 pac. Someone wants to send me a self addressed stamped envelope to cover postage I'll give them to you if you'l use them and not sell for a profit. Surely 3 or 4 stamps would cover shipping. I think there Noxturnals. Again there flat ,not moon. No pics
