This revolutionary kit consists of two micro-thin layers of polyurethane with a non-toxic lubricant sealed in between. When the Breast Chek is placed on the breast, the bottom layer gently adheres to the skin and remains stable allowing the upper layer to slide freely underneath your fingertips. As the upper layer slides freely over the bottom layer, friction is greatly reduced. This results in what is called “sensory touch magnification,” meaning that your sense of touch is greatly improved, which leads to more effective and accurate breast exams.
