Stainless steel iron set, a set of 4 from 6 to 9 iron. I am selling it because I bought a new one. Perfect for beginners. The shape is forgiving, and the feel is good. The grips are still usable, and there is no looseness in the heads. - Set contents: Iron set - Material: Steel - Grip: Rubber grip - Condition: Used The following is quoted from the internet: ■ Features of TaylorMade Burner PLUS Irons ◆ Low and deep center of gravity design adds to the ease of getting the ball airborne and stability By distributing weights widely on the heel and toe sides of the sole, along with a wide sole and undercut cavity structure, an ideal low and deep center of gravity and high moment of inertia are achieved. High trajectory is easily obtained, and distance and stability are also improved. ◆ Multi-functional sole adds to the ability to handle lies The unique sole design, which slants the trailing edge, is adopted. Despite the wide sole, it is easier to use in various lies, demonstrating easy operability and good turf interaction. ◆ SuperFast Technology adds to swing speed The lightweight original shaft "RE*AX SUPERFAST BURNER PLUS" developed specifically for this model accelerates swing speed and easily achieves long distances. ◆ Sound Optimized Cavity Badge adds to a comfortable feel By attaching the Sound Optimized Cavity Badge, a soft yet firm feel and a pleasant hitting sound are achieved.
