Developed as a safe, affordable, non-surgical alternative to expensive medical procedures and pills, this manual pump is the easy way to instantly enlarge your penis without any negative side-effects. With each push of the EZ-Grip pump trigger, a super-strong vacuum is created inside the chamber, forcing your erection to quickly expand its length and girth. Once you penetrate the smooth, flexible TPR opening, you'll quickly discover throbbing, rock-hard erections that feel great and swell with power! When you've reached your desired size, simply push the quick-release button at the base of the trigger to instantly relieve the pressure. The soft TPR sleeve forms an air-tight seal against the skin, creating incredible suction and amazing results, while the transparent vacuum cylinder allows you to see your cock get bigger and fatter by the second!

The tight squeeze will prolong ejaculation, help maintain your erection, and extend the fun. When you're done, remove the sleeve and thoroughly clean the tube with toy cleaner and warm water, restoring it to like-new quality. Tube Length: 7" (18 cm), Tube Width: 2" (5 cm).
