The pretty love BI-026274M is an amazing penis sleeve that makes your penis stronger. Made from silky-soft TPE material, it's soft and stretchy, yet sturdy enough to stay securely in place. It adapts to any penis size and fits snugly against the skin, helping to retain blood and resulting in longer, stronger erections. Ideal for progressive potency training, it prolongs the sweet time by reducing stimulation of sensitive parts of the glans and delaying ejaculation. Simply slip it over your penis for ultimate satisfaction. It's also made of TPR material and is waterproof.
