Kwik-Moving Quick Relief Patches are large-sized therapeutic patches designed to provide pain relief by activating body heat. Each package contains 2 patches measuring 11.5cm x 19cm, making them suitable for covering larger areas of discomfort. The patches work by activating the body's natural heat response to help alleviate pain and discomfort. They are specifically formulated to provide relief for muscular pain, arthralgia, lumbago, rheumatism, and sciatica. The large size (11.5cm x 19cm) makes them particularly effective for treating broader areas like the back, shoulders, and thighs. The product is manufactured by NNS.
