High-quality iron set, 5 pieces, providing precise feel and stable performance. - Model: Iron Set - Quantity: Set of 5 - Club Numbers: 5, 6, 7, 8, 9 Thank you for viewing. This is a set of 5 irons, numbers 5-9, from Callaway Big Bertha. Shaft: NSPRO950 R The grips (with a back line) look clean, but have deteriorated with age. Although it's an old model, as you can see from the shape, it has a low center of gravity and a wide sole, making it very easy to use. I think it's suitable for those who want to get the ball up in the air. Thank you.
