PosTVac Ultimate Constriction Rings improve erection quality by restricting blood flow from the penis, making your erection harder, last longer, and more sensitive. The tabbed wings simplify placement and removal. PosTVac Rings are compatible with PosTVac Pumps but are as effective as a stand-alone sexual performance enhancer.
Enhance sexual performance and erection quality without side-effects
Available in Maximum Tension (.23"), High Tension (.31"), Medium Tension (.43"), and Low Tension (.55") sizes
