Nanjingtongrentang 発熱パッド　5枚入 1 箱

First time buyer, got this for my daughter. She has bad cramps during her month, and will she how it goes.

These are AMAZING! I tore my ACL last year, and my knee tends to get sore after walking or standing for long periods. These help me out so much! They warm up quickly and stay warm for around two hours. They help relieve a lot of the pain and discomfort

first time trying, hope match medical usage.

These don’t get too hot as some heat patches do. Bought two more boxes after testing them out
