Pop it, lock it, drop it - this cage is more exciting than birthday cake. A non adjustable 1. 8" diameter, this steely prison provides an inch perfect fit. Sit tight. A simple 2 piece design makes this easy enough to use for even the most rookie inmate. Clamp the 1. 8" diameter ball ring around the back of his balls, taking extra caution not to pinch the delicate skin (unless he likes that). The spacer measures up at just over 1/2 inch and allows 1-2 inches of space for your balls to hang low. Take a deep breath and slip the enclosure on your sweet chariot, which features plenty of room for easy cleaning, urinating and ejaculating. Last but by no means least, pop the padlock in place to prevent this prop from scoring.
