I have been using this for years. After a long night of dancing on high hills, I apply the patches to my feet and sleep with the it. Feel much better in the morning, it really saves my feet.
I told many of my friends about this product and they are all happy to use it.
It helps me a lot to release my legs pain, and tension.
I always buy the product when I go to Japan. When I finish the product, I order it. When I order from U.S., it costs me more. It is a great product, but I prefer buy it in Japan.
