Rimba Electro Play 2 x flexible rubber body cups including lead wire. The cups are both Bi-polar. Because the distance between the electrodes on cup is minimal, there is no flow towards the heart, if worn on the breast  for example in a bra. The cups can be worn on different places on the body, breasts, abdomen, buttocks. The cups are not adhesive so they should be put under a tight worn garment so that the cup stays securely in place and there is a good contact is made. This can be in pants, under straps or belts. The use of contact gel helps to create an optimal contact between skin and electrode.
