Thank you for viewing. Omron Low Frequency Therapy Elepulse Long Life Pad Compatible 449 Replacement 1 pair (2 pieces) only Electrode patches can be applied to therapeutic devices, are adhesive, can be used on various parts of the body, and can be used repeatedly for a long time. The metal point on the top can be connected to the therapeutic device with a snap fastener. The number of times the electrode pads can be used depends on the cleanliness and oiliness of the skin, so it is best to wash the skin with soap (alcohol is also acceptable) before use. Cleaning the skin will give better results and increase the number of times the electrode pads can be used. Works with most Omron massagers.
