Made from body-safe Elite Silicone this dual-action stamina ring easily stretches for maximum comfort and proven results. The small ring wraps snug around your shaft while the large ring wraps around your penis and testicles. Try both rings pulled behind your whole package for an extra tight squeeze. The dual rings work together to gently put a clamp on performance letdowns and make you bigger thicker and harder than ever before. Powerful vibrations will tickle and tease her clit and send the incredible pulsations all the way through his shaft. Requires 3 AG13 batteries included. Toy cleaner and lotion included.
