Just microwave for up to 30 seconds or place on a radiator for a minute to heat them through, they never go completely cold.
Small enough to fit in your pocket or gloves and you have 3 options, just with organic wheat, wheat & lavender or wheat & rosemary (great pain reliever)
There is a pair per pack and made from pure cotton fabric.
Don’t suffer with cold hands this winter, these help with the symptoms of Raynaud’s disease and poor circulation too.
