The Forto F-20 model offers a double penis ring with testicle expander effect. Place the first magnifying glass at the base of the penis and the largest around the testicles. This model allows you to obtain an erection that is more rigid to the touch and improves your performance time. The second ring will put pressure on the testicles forcing them to stretch, thus making the testicles more sensitive to stimulation.
Stretchy and soft to the touch, the F-20 model is comfortable to wear and safe.
