This a realistic stroker that comes in six colors. Best for folks with some growth.  (check out our reviewer's take on this here - link takes you to YouTube) The Stroker is a flaccid, flexible, and lifelike penis-shaped masturbator made from premium silicone and designed to be durable, flexible and comfortable. The details and the soft texture with internal relief will surely please. (Growth of the "dickclit" is necessary for optimal use.) We recommend the use of a water-based lubricant. Please consult the F.A.Q to know the information related to the maintenance of the prosthesis. Length: 4.5 in / 11.5 cm Circumference: 5 in / 12.5 cm Diameter of the cavity: 2 cm   Do not to unroll and stretch the stroker excessively like a sock to avoid premature tearing.   Note that these are handmade items and there will be air bubbles and the finish on the end may have some flaws and the hole may not be directly in the center of this item. These situations do not affect the stroker's suction capacity or durability and are not a valid reason for return. Also the colors may not look exactly as they appear on your computer screen.
