[Weight Adjustment] Callaway weights are designed to enhance the performance of golf clubs. By using weights of different masses, you can adjust the club's balance and improve swing stability. [Various Weights] This set includes four weights: 3g, 5g, 7g, and 9g, allowing players to choose the optimal weight according to their needs. This enables customization tailored to individual playing styles. We also offer a 4-piece set of 11g, 13g, 15g, and 17g, which can be purchased together for a wider range of trajectory adjustments. Even gram weights such as 2g, 4g, 6g, 8g, 10g, 12g, 14g, 16g, and 18g are commonly available, but odd gram weights are rare, so we recommend acquiring them before they are gone. *Please note that Callaway does not offer genuine screw weights of 1g.
