■ Product Description Set of 6 cute smiley face vibration dampeners! In addition to functioning as vibration dampeners for tennis rackets, why not use them as a fashion accessory? ■ Notes The second image is only to show the size of the vibration dampeners; the racket itself is not included in the sale. ■ The Pros and Cons of Vibration Dampeners There are various types of vibration dampeners. Some are string-like and threaded through, some are tied, and others are block-shaped like these. Also, whether to use them or not is a matter of personal preference. Kei Nishikori is a user! He uses the famous Quake Buster by Kimony. Roger Federer doesn't use them, and Rafael Nadal doesn't either, but some Babolat rackets have vibration-dampening functions built into the grip and shaft, so he doesn't need to use one. Using a vibration dampener has the advantage of absorbing the impact when hitting the ball, reducing the risk of wrist tendinitis and tennis elbow. On the other hand, a disadvantage is that it can be harder to tell if you're hitting the ball in the center, creating a trade-off. You should choose based on your preference and the condition of any injuries. These vibration dampeners are for people who "want to dampen the vibrations a little, but don't want to lose the feel of the shot." Please consider this when making your purchase. ※ Hashtags for other listings All items for sale: #ikurachan_ALL Strings for sale: #ikurachan_vibrationdampener ※ General search hashtags #vibrationdampener #damper #tennis
