4, 5 and 6 Hybrids are graphite shafts. The 7, 8, 9 and PW are regular steel shafts. They're a Hybrid set of irons, so the faces have fat cavity backs, making them very forgiving and easy to hit. Plus, they're in excellent condition! I was taught to take care of my clubs and have always done so for all my sets! I'm asking $250, I'd love to address any questions or concerns you may have.
Cheers,
Mike
