I've used this, and there are stickers in it. I didn't insist on soaking my feet. I tried to wear high heels, and my feet hurt, but it didn't hurt once. As for other effects, I didn't insist on it and I didn't have much experience. But that post is really good. My cervical vertebra often hurts. I posted it once, and it was much more comfortable the next day. I thought it was quite good, so I put a wealth bag on my mother, which was effective in promoting blood circulation and removing blood stasis. I didn't expect 15 days to be flat. Really disappeared. Then my mother asked me to buy 20 boxes and took all the stickers away, saying that it hurts where it hurts. Leave all the foot bathing to me. I'll answer this question when I'm finished soaking my feet.
