These Two Stage Cylinders are for the advanced pumper to enlarge both penis and scrotum in the same cylinder. Two stage cylinders are sized by measuring with a string around the penis and scrotum, while erect. (near where you would wear a penis restriction ring.) Use this measurement with the chart in the link above to determine the first stage size. You should have ample space in the second stage of the cylinder. How it works:
  • Simply place your cock and balls into the cylinder and attach the hand pump to the release valve.
  • The smaller opening into the larger chamber keeps much of your abdomen from being pulled into the cylinder. The larger chamber allows for plenty of extra room for expansion.
  • You can then pump your penis and balls to a desired size.
Notes:
  • Be careful when using this product and other penis pumping accessories, make sure you perform this procedure in a safe manner, do not try to pump your penis to be larger than the container. Many men have been able to pump their penises to 8 inches in circumference, and scrotum to 10 inches in circumference.
  • This product does not include a hand pump or hose!! You may order one here. (The hose is included with the pump.)
  • Numbers on the drop down menu's represent inner measurements of diameter and length.
