£30.00

Additional lower lengths are available to help in finding the perfect fit, or for use with multiple players. Additional lower stages complete with liner.

Sizing:

Internal diameter (40mm or 50mm): The size refers to the internal diameter of the lower section. 40mm is by far the standard size.  Due to the way the milker works the sizes are not that critical – as long as the penis will fit inside the acrylic tube when erect. Diameter is calculated by dividing circumference by 3.142 (π)

Length: The Length of the lower section is available in 95mm, 115mm, 125mm,140mm, or 155mm lengths – measured from mid way in the acrylic constriction to the base of the SPT. The length chosen should be the length closest to, but longer than, that of the erect penis, measured from abdomen to tip. This enables the head of the penis to be drawn through the constriction with each pulsation of the Milker.
