Kao Steam heat sheet めぐりズム 蒸気の温熱シート 下着の内側面に貼るタイプ ５マイ 花王

I LOOOOOVE this thing. Perfect for when your period cramps are on its worst behavior. The heat effect in these is recognized for improving circulation, relieving muscle and nerve pain, and supporting digestive function. I also will sometimes use for lower back pain.
