Rimba Electro Play self-adhesive gel pads with push-button connection. This package contains 2 unipolar pads. These pads are flexible and can be used up to 15 times, depending on how clean the gel stays. A clean, hair-free skin ensures the best contact. A single pad is unipolar, so you must use 2 pieces or a pad and another unipolar accessory to create an electric shock. Always be careful, do not use if skin is broken or irritated, if you have heart problems or are pregnant.
