JESSI is a discrete and petite super powered and versatile mini bullet. Compact in size, the silicone-coated JESSI offers 10 modes of vibration, pulsation, and escalation at the touch of the power button located at the base - just press and hold for 3 seconds to turn on or off, then press to change the mode. It's sized just right, and can be used on its own or as a replacement bullet in other toys. The USB rechargeable JESSI is waterproof for fun in & out of the water and easy cleanup.
