The Triad is a set of three cock rings in graduated sizes, attached to one another to create a versatile system to improve stamina and achieve firmer erections. The rings can be folded to create an overlapping stack, or arranged in different configurations to create slings, cages, or ball stretchers. The Triad is made from stretchy and body safe silicone, and is 6.6 inches (16.76 cm) long.
