Thank you for viewing! (^-^) This is a 5g weight for Scotty Cameron putters. ※ This product is a compatible product. ※ Wrench sold separately. Listed separately. It's a new, beautiful item (^-^) Compatible models: Fastback, Fastback 2, Roundback, Newport 3, Squareback ※ Please note that it is not compatible with Fastback NO.1, 2019 model TERYLLIUM T22 Fastback 1.5 The weight is usually 10g lighter than the standard 15g, so the feel after installation will change considerably. Reducing the head weight improves operability and is recommended for those who prefer a putting stroke that emphasizes the feel of the hands. Also, women will experience less being thrown off by the weight of the putter, increasing stability (^_^*) I also have many other golf goods for sale. If you purchase multiple items at the same time, we can offer a set discount if you comment beforehand, so please take a look (^_^*) 〓Product List〓 #kuu-shop Since weights and wrenches are often relisted, if you "like" the item, please also follow my page (^-^) Titleist Scotty Cameron GOLF Putter Weight
