Intimacy Heart Massagers are designed for intimate use, with the primary use being for when a person gives a lover an intimate massage. They also are great for self-care, whether it be an injury or cramps. To activate a heart massager, break the metal tab inside of the heart and then a reaction inside heats up the heart. After the first use, simply boil the massager (for about 10 minutes) to reactivate. There are three colors available: red, purple and blue.
