Full instructions are included, but the basic process is simple, mix up the molding powder and water in a bowl, and pour into the tube that doubles as packaging until you're ready to use it. Since your or their penis needs to be fully erect - the harder, the better - use your favourite means to that end (a cock ring can help), and then insert the penis being replicated into the natural algae-based molding powder mix. Hold the tube steady for a minute or two, then remove yourself. Completely pour the combined contents of both jars of silicone mix into the mold. Next, position the vibe in the center of the filled mold and let it all set.
What you'll be left with is an exact copy of your favourite cock with all details intact AND vibration that will make the whole thing buzz for your perfect pleasure. Make sure to follow the very detailed instructions for best results. The appearance of your Clone-A-Willy will vary, deeding on the size and shape of your/their penis. Phthalate and latex-free. Vibe requires 1 AA battery, which is sold separately.
