This is one dildo that will surely never be misplaced in the dark! These original glass toys from Forbidden Novelties are crafted hollow and filled with black-light responsive, glow-in-the-dark liquid. Available in either an 8-inch ribbed design or a 10-inch studded design, each dildo is smooth and curved just enough to facilitate comfortable use as a G-spot or prostate toy. Like other borosilicate dildos, the Glow Daddy can be cooled in ice water or heated in warm water, and it can be easily cleaned with soap and water or in the dishwasher. Consumers can choose between pink, sky blue, or purple.
