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 remains. Clean, hair-free skin ensures the best contact. A single pad is unipolar, so you need to use 2 pieces or one pad and another unipolar accessory to generate an electric shock. Always exercise caution and do not use them if the skin is broken or irritated, if you have heart problems, or if you are pregnant.
