The Cusco vaginal speculum is a large speculum that makes it possible to look inside the vagina. The toy can open the vagina as wide as you want. The speculum is adjustable and can be locked at a certain diameter. It is made of strong stainless steel, so the material won't bend or break. Metal feels cold, but it can be warmed up, or cooled down even more, by putting it in a bowl of water for a few minutes. With this toy, you can use any type of lubricant.
