    Pumping is stimulating, feels great, and has both short- and potential long-term positive impact on genital size.

    Each cylinder is made of industrial-strength acrylic, taper slightly from the opening to the top, and have a flared base. a quick connect, airtight valve makes it easy to connect and disconnect your pump without breaking the seal.

    Sizes are shown below, with the first column being the cylinder size/diameter and the second column being the inner circumference of the cylinder—or whatever it is you're putting in it. Most guys use 1.75" to 2.25" for just the shaft, and the larger sizes for when you want to put everything in. Each cylinder measures approximately 9" from base to the valve.

    PLEASE NOTE: This item includes the cylinder only. For this to function, you must have a compatible pump, such as the Heavy Duty Dry Brass Hand Pump with ANSI Gauge sold at FullKit.com.
