I have never believed in this type of products before but one day my friend shared his Iyashi Bracelet with me because I had a large mosquito bite that was swollen up. After wearing the bracelet for an hour it was completely gone and I was in shock how well it worked. A few days later I had some deep tissue soreness in my elbow which usually lasts about a full day. Again I put the Iyashi bracelet over the affected area and within 45 minutes I pain free. The fact is this stuff works.
