This sleeve is made of translucent pink silicone. It is very stretchy, 6 1/2 inches long and fits perfectly in the palm of your hand. The ribbed head provides better grip and prevents slippage. The entrance and interior tip both have raised nodules to increase stimulation on the head and base of the penis. This toy also has three extremely tight suction chambers. These three rings have their own set of nodules that massage and create positive friction along the shaft. The sleeve is dense enough to be turned inside out for cleaning. Use lots of lubricant with this product. We offer this toy as a tool for wives to stimulate their husbands - awesome for hand jobs.
