With this silicone penis ring set, you'll last longer and stay harder! With three rings in different sizes, you can try out three different sizes and find the perfect fit. Choose colors that match your skin tone for a more neutral look, and enjoy high-quality silicone that is phthalate- and latex-free and best used with water-based lubricants. Slide the rings over your penis, your testicles, or both. Use them individually or combine them for extra pressure and more sensation! Rub some lubricant on your penis and testicles and add a little more to the inside of the rings. Slide one ring over your testicles and then pull your penis through it. It will now fit around your penis and testicles, behind the testicles. Wear it only around the testicles to stretch them. Wear it in front of the testicles by sliding it down the penis so that it sits in front of the testicles. Combine them for different pressure and different sensations! Dimensions: Inner diameter: 30 mm, 35 mm, 40 mm. Material: Silicone.
