Review of using Nichiban Leichtspoco for shoulder muscle cramping pain

I received a Nichiban Ryoichibo Ko gift from a Japanese person. I had just been keeping it at home, but recently my shoulders were very stiff due to excessive work, so I tried using it. Originally, I was planning to go to the pharmacy to buy a patch, but since it was too late, I used the Ryoichibo Ko that was in the corner of the room. It seems to be much more effective than Korean patches. It helps with blood circulation, quickly relieves pain, and feels refreshing. Once I finish what I have now, I plan to buy more. In the future, I think I will only use Ryoichibo Ko for muscle pain.
