What is the difference between the Onyx and Pearl devices?
The Onyx is a male masturbator which can send and receive signals from performers who have a compatible device, such as a Pearl or Pearl2. It features a removable sleeve which can be replaced. The sleeve is made Fleshlight using the same synthetic skin material popularized in their main Fleshlight product.
The Pearl/Pearl2 device is a dildo/vibrator which has sensors to recognize touch.
