Protective cover made of nitrile rubber, featuring a plastic ring at the closed end that "holds" the female condom in place in the back vaginal vault to prevent it from slipping out during intercourse. There is also a plastic ring at the outer end that is placed around the labia to prevent the female condom from sliding back into the vagina. Moist, transparent, 3 pieces per pack. The female condom was invented in the late 1980s by the Danish pharmacist couple Hessler. Since its market introduction in 1990, it has been the only product worldwide that allows a woman to protect herself from sexually transmitted infections and unwanted pregnancies independently of her partner. A female condom is a soft, gently conforming sheath made of nitrile rubber that lines the inner wall of the vagina like a very thin second skin. It has a soft ring at each end. The ring at the closed end is used for inserting the female condom and ensures that it stays properly positioned during intimate intercourse. The outer ring remains outside the vagina and covers the labia. The combination of the natural secretions of the vaginal wall with the lubricant on the outside of the female condom ensures that it adheres well to the inner wall of the vagina, which is why it can be referred to as a very thin second skin. The high-quality material nitrile rubber is a durable and well-heat-conducting thin material that is significantly more skin-friendly than latex.
