Prior to purchase
Be sure to review our Sizing Guide when measuring the penis and scrotum for proper fit guidelines.
CB-X chastity kit parts are interchangeable with all CB-X cock cages so you can mix and match your complete chastity cage kit with any other CB-X chastity cage that we offer.
Accurately measuring penis length and diameter will help ensure the correct chastity cage size. The two main factors to consider when choosing a cock cage are 1) anatomy size and 2) fit preference. To achieve a tighter, more restrictive fit, exact measurements might not be as relevant.

To activate your CB-X glow-in-the-dark chastity device, it must be exposed to light, which charges the phosphors and causes them to re-emit light. The amount of time it takes to charge this glowing chastity cage depends on the type of light used. To preserve the glow-in-the-dark feature, do not leave any glow parts under light for extended periods of time.
How to charge:
3-4 mins of UV/Blacklight
7-8 mins of direct sunlight
21-23 mins of fluorescent light (strip lighting or energy-saving bulbs)
24-26 mins of incandescent light (standard filament bulbs)
