Just because there's a hole......... or just the tip!

There's some confusion over how the devices are measured and how they should fit.


The area in the inner cone is 10mm smaller then the device measurement

 example: 35mm car-1 the inner cone hollow area is 25mm

if you are in the 35mm car-1 size it'll be just the tip and nothing more.


The area in the inner cone is about 5mm smaller than the device measurement. the retainer shout cover about 1/2 to 2/3 of the glans. the retainers are pretty forgiving on sizing.

Using my tape measure / sizing guide will point you in the right direction.
