Roger Federer RF Logo Tennis Dampener *This is for two dampeners. There are three types available: please specify from ①, ②, ③, or ④. I will create a dedicated page for you to purchase from, or you can purchase directly and specify the type in the transaction message. If no type is specified, we will send ① and X. Please ask if you have any questions m(_ _)m. These are slightly larger dampeners, and they attach securely, so they are less likely to come off when you hit the ball. As they are made in a certain country on the neighboring continent, there may be variations in quality. Please understand. If you wish to add more, each additional one is 400 yen.
