3.5" BOSTONPUMP STANDARD DESIGN. PENIS ENHANCER CYLINDER

3.5" BostonPump’s Standard Design penis vacuum cylinder. This design has a classic upward flared neck with built in cock-ring. The Standard Design penis suction cylinder is among the strongest penis enlarger cylinder in our catalog. The built in cock-ring is designed internally and is an integral part of the cylinder. Because of the cock-ring, the cylinder stays nice and tight without sucking in much of your scrotum or squeezing the base of your groin. By having a built-in cock ring, the opening diameter of the Standard Design cylinders are somewhat smaller than the other BostonPump penis suction cylinders. It is for the same reason that the standard cylinders are capable of more intensive suction than the other models without this feature.

-Pros: Capable of high suction, Suitable for Hydro-penis pumping, Built-in cock-ring. 

-Cons: Requires full shaving for best suction.

Available lengths: 5", 7", 9", 10", 12", 14", 15", 16", 18", 20"
