Thank you for viewing! (^_^*) This product is a compatible product. It is a new item, so it is in beautiful condition (^-^) Confirmed to fit genuine putters. This is a single weight, so a wrench is not included. Wrench set products are listed separately. The weight is usually lighter by 10g increments from 15g, so the impression 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, for women, the putter will be less affected by the weight, increasing stability (^_^*) Furthermore, the Scotty dog mark is not widely available, so it is recommended for customizing your putter.
