Here’s a great product that I highly recommend. Today after a long day doing a garden walk all over Key Largo, i was in real need of a good, strong heat pack. I find that often heating pads are not hot enough but these heat up instantly and so, so hot and nice. The large ones are fantastic for low back, shoulders and more. The small ones are discreet and can be placed onto sore spots anywhere.
The price on these is awesome, only $9 for 2 large and 4 small. They are activated by flexing a small metal disc and heat up instantly and are refreshed simply by placing them in boiling water.
I personally use these and endorse them and have not been paid to do so or provided free items.
