Pack of 30 self adhesive patches for directly grounding specific parts of the body.While grounding any part of the body can be beneficial, the relief has been found to be faster when grounding is applied directly to the area to be treated.Patches are 50mm x 25mm (2" x 1"), similar to the ECG/EKG electrode patches commonly used by doctors for testing purposes. Although they are sold as disposable, each patch can be re-used a few times if peeled off carefully and placed on some plastic. Replacement packs of patches are available.Comes complete with a coiled connection cord, plug sold separately.The supplied cord is approximately 1.8m (6ft) long when unextended. It stretches up to 6m (20ft), although when stretched to this extreme it will tend to pull the patch.
