If you love the idea of molding your own dildo with the Clone-a-Willy Kit, but you or your partner are well-endowed enough to need some extra silicone, grab the Clone-a-Willy Kit Refill. It's simple - this refill gives you enough extra material that you'll be able to create a dildo as wide and/or long as the penis in question. Done and done! To be used only in conjunction with the Clone-a-Willy Kit.
