The Pink Jellie Prober is one of the many attachments available that are interchangeable with the "Vac-U-Loc" system. This is a state-of-the-art strap-on system that features an adjustable waist up to 44" plus an open crotch for maximum comfort, easy access, and non-slip action - all designed to give you command and control for your erotic pleasures. The Pink Jellie Prober has always been included with the Juli Ashton Ultra Harness, but it is now available separately for your other "Vac-U-Loc" harnesses as well. It has soft curves and minimal ridges around the head for maximum comfort. This will be one of the most comfortable devices you will ever have the pleasure of using.
