*Inserts are sold individually not in pairs and fit current model R8™ and R8 Plus™ only. Want a slightly softer massage experience? The SuperPlush’s unique shape and specifically formulated plush material was developed to provide a gentler feel while still providing a flushing effect and deep massage. You can use two SuperPlush Inserts on both sides or try one, while the other side is the Standard Insert or SuperDeep Insert for a unique feel. Available in Glacier White color. The R8 Inserts were designed to make the R8 and R8 Plus more versatile. With the new SuperPlush and SuperDeep Inserts, you can customize the feel of your R8 or R8 Plus exactly how you want it. Feedback from athletes was vital in the development of each insert. Explore unique ways to customize your R8 or R8 Plus with different combinations of Inserts. One Insert is for one side. Add two Inserts to make it a pair.
