A very uniquely designed dildo, the rocky road from Phallix is lined with a plethora of sensuous nubs that are great for both vaginal and anal penetration. This high quality, medical grade glass is tempered for durability and polariscope tested. Used to identify and evaluate strain and irregularities in glass products, a polariscope ensures that the product is built to last a lifetime and won't crack under pressure. The professionally created dimensions, including the smooth rounded head and perfectly angled shaft, also make g-spot stimulation comfortable and consistent. Though glass toys are thick and heavy, they are usually more efficient, as the nonporous material makes lubricants last longer, and cleanup quick. Hypoallergenic and doctor recommended, the rocky road never made a bumpy ride sound so good.
