POPBANDBig Hug Heating Patches for PMS Menstrual Cramp Relief

Unfortunately it really works for 12h at a reasonable warmth level. It's so expensive! Much more than other brands and the ingredients are super cheap and simple so idk why theirs work better than others, but it does. Way too expensive, but the only one that works well enough to be worn at school all day to relieve menstrual cramps.

These ones actually last 12 hours, if not longer. They get hotter than any other patches I've tried, which is perfect. Genuinely the best. If you put them directly on skin, you can get a second-degree burn, which is about as hot as I could ask for!

I was skeptical about buying these, thinking they wouldn't last more than an hour, but I've been proven woefully incorrect. The patches are larger than I expected, which is good! Once you open the package it will start heating up it takes a few minutes to get really heated, if you're looking for something that gives you the heat of an electric heating pad this isn't it, it gets hot enough to turn your skin red but its a very comfortable manageable heat, a little bit hotter then hot hands. So far a single patch has lasted 10 hours and has only cooled down a little, you can rub the patch to generate more heat when it does cool down. Obviously don't put the adhesive side directly on your skin, It's to be placed on your clothes. My only criticism is that the adhesive could be stronger, I've taken it off and on to readjust it, and it still sticks fine but could be better.

Temperature changes travel faster than pain, so this is a great product to distract from the pain while feeling comforting!Ordered multiple times! Just stick the sticky side to your granny panties and good to go.

These are great they last all day or all night!!
