Target specific areas with the elbow like design to apply the deep force needed. For maximum intensity, use two SuperDeep Inserts on both sides of the R8. Or for a unique feel, try one SuperDeep Insert along with the Standard or SuperPlush Insert on the other side. Available in Boulder Black color.
