These Electra pads are self adhesive and can be placed across any desirable area. You and your partner can wear one pad each on the buttock or inner thigh area and then have intercourse like you have never done before as the stimulation current flows between your two bodies. Ensure that bodily contact is kept below the waist. Re-usable up to six times by the same persons, supplied in a pack of four. The 2-inch square surface of each pad conducts electro stimulation to create erotic tingles and pulsations that enhance erotic sensations.
