Five u-ring sizes and multiple pins with corresponding spacers are provided in the kit to help find your custom fit. 

Product Features:

• 3¾ inch cage length*
• 1½ inch inner diameter
• Made from body-safe medical-grade polycarbonate
• Durable, hygienic, hypoallergenic, and lightweight
• Comfortable and customizable fit
• Functional opening for urination
• Vented cage design for easy cleaning

Note: "Cage length" Is the length of the cage itself. (Not from the back of the ring to the end of the cage.)

To measure yourself for a cage, you will use two items: 

• A fabric measuring tape
• Standard 12” ruler

Measuring Length: Using the standard ruler with a flaccid penis, measure from the base of the shaft against the pubic bone to the tip of the penis head.

Measuring Girth: To measure the inside diameter (I.D.) you will need to measure the circumference of your penis. Use a fabric measuring tape and wrap it around the girth of the flaccid shaft, ensuring that the measuring tape is snug, but not pulled too tight. Then divide this measurement by π (3.14) to find your penis diameter. Knowing the diameter of your penis will help when choosing a chastity device because you will compare it to the inside diameter (I.D.) of our various cock cages.

For Accuracy: Do not take this measurement directly after showering, and/or with an erect (or semi-erect) penis.
