Cora Heat Relief Patch - 2 Pack - Soothe Cramps for up to 8 Hours with Heat from Activated Carbon - Adheres to Your Clothes to Ease Cramps Exactly Where You Need it

These really helped my teens cramps. She wears them at school and during her sporting events. They stay warm for a long time.

These patches really help with cramps. Make sure you put them on clothing, they cannot go directly on your skin.

Works great!

These get slightly too hot IMO, but I think I might have a heat sensitivity. For others, it’s very soothing. I used these at work & they typically last about 6-8 hours. The heat peaks around 4 hours, then slowly tapers off. I’ve purchased these time and time again. They do get old & not effective if not used within a few months of purchase, so I wouldn’t keep them as an emergency stock. There’s great during winter or when wearing a few layers of clothes. I have definitely recommended these.

These are amazing. They help with my back pain
