This is a nice Electrode Pad/Cable Combo with 4 Large and 4 small durable and flexible electrodes that are excellent for applying around joints such as wrists or elbows. These pads can be used for areas of the body that are flat, like back or thighs. They are great quality and come with a thick layer of non-irritating conductive gel that adheres well to your skin, but leaves no sticky residue when the electrodes are removed. Also included are 8 smaller pads, nice for treatment/therapy for more concentrated area of current.
