This SPT has an adjustable telescopic length to optimise sensation. Simply choose an internal diameter.
Internal Diameter (40mm, or 50mm): The size refers to the internal diameter of the SPT. 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 the circumference by 3.142 (π).
An adaptor kit is also required (+£18) for use with the original Surge Milker. This can be ordered HERE.
