Our first new ball toy in quite a while, this device uses two straps and buckles to attach the leather stretcher to the balls. You can then add the weights of your choice to the two "D" rings. I find that there is quite a difference in the sensation between one weight on each side, and the same total weight on both, because of the effect of pulling the two rings together. Try it, we think you'll find this a great piece of gear.
