Popmask Bare Hug Self-Heating Patches, Heat Therapy for Pain Relief in Back, Neck & Shoulders, Lasts Up to 12 Hours, Heats in 30 Seconds, 3 Patches

Ok

If you have major period cramps or have back pains during mother nature’s monthly visit these are an absolute must! They work well enough for me to even use with back pain. I have put these on, fallen asleep for a couple of hours, and woken up with them still being hot. I attempted to use the midol patches and compare them and I can say these absolutely blow midol’s patch out of the water!

First time using, amazing warmth, lasting morning to night!! I want more!
