The clear vacuum cylinder allows you to see your growth! The thick, heavy grade acrylic tube is marked with metric graduations to measure your results.
Once you’ve reached your desired size, simply press the quick-release button under the power button to instantly relieve pressure. Or, press and release the quick-release button intermittently to enjoy milking sensations that feel just like oral sex!
Unscrew the pump cylinder from the pump motor, then clean the tube with Refresh Toy Cleaner and warm water. Do not submerge pump motor.
