The Cusco vaginal speculum is a large speculum that allows viewing the inside of the vaginal cavity. The device can open the vagina as wide as desired. The speculum is adjustable and can be locked at a specific diameter. It is made of sturdy stainless steel, ensuring that the material will not deform or break. The metal has a cool sensation but can be heated or cooled further by placing it in a bowl of water for a few minutes. With this toy, you can use any type of lubricant.
