Hello, the foot-warming patch and the baby-warming patch are actually the same, but their names and sizes are different, but their functions are the same, that is, relieving joint pain, preventing frostbite, and generally having a fever function. Belle Old Beijing Foot Warm Sticker is recommended, which can not only dredge blood vessels, maintain heat, but also detoxify and eliminate dampness, and the effect is good. I hope I can help you.
