Standard Rings: 8 mm thick. These work for most people.
XD Rings: Extend forward by an extra 2.5 mm. This tightens the gap, and also makes the rings more rigid. Good for people with smaller balls to prevent escape.
Curved Rings: 5 mm backward curve at the bottom. Good for relieving pressure under the scrotum. Note: People with smaller balls can be more likely to slip through the gap with a Curved ring, defeating the purpose of the device.
