Our knee strips contain peppermint oil, Angelica. It soothes pain and soothes skin gently with soft and comfortable care. Its application is simple: Step 1, clean the area of the skin that needs to be applied to ensure that the skin is dry. Step 2: Take the knee care tape out of the package, gently remove the protective film on the back, and then apply it to the knee, ensuring that the tape is tightly fitted to the skin to avoid wrinkles. Step 3, wait 8-12 hours, then gently tear off. And it makes our knees stronger and stronger.
