They are also highly adhesive, self-adhesive, and reusable. EMS Gel Pads: Replacement gel pads for EMS muscle stimulators, compatible with most EMS devices. 0.8 mm hydrogel stickers with high conductivity ensure close contact between the skin and the EMS muscle stimulation unit, delivering strong conductivity and effective performance. This size fits most electrical stimulation equipment. Long-lasting Viscosity: Professional muscle stimulation gel pads offer a long service life and can be used approximately 30 times. The number of uses may vary depending on skin cleanliness and oil levels. We recommend cleaning the skin with alcohol before each use to extend the life of the product.
