The style of Sunrise's frosted head g-spot wonder is so popular because it's intended to target the G-Spot as most of the curved styles have added ribs to stimulate the clitoris at the same time. The location of the ribs allow you to rub them over the clitoris as you penetrate in a circular motion to reach the G-Spot and the double ball end is very comfortable and easy to grip to maintain complete control. The clear solid Pyrex shaft is 7 inches in length and 1 in diameter and curved just before it reaches the 1 1/4 inch diameter head. The ribs are smooth and nicely rounded adding approximately 1/4 inch to the shaft diameter. The double ball end is approximately 1/2 inch larger in diameter than the shaft and features a smooth and a frosted ball on the end for a little more grip. The Vivid logo is etched on the shaft signifying that it's one of the official glass sex toys of Vivid Entertainment.
