You can either heat this pack up in the microwave or cool it off in the
freezer depending on which type of therapy you need. Great for sore muscles,
arthritis, nerve damage etc. I use mine everyday and I put mine in the
microwave for one minute and 30 seconds. Times do vary as microwaves are not
all the same. Please be careful when removing it from the microwave, as it
could be very hot.
I love the moist heat that this pack delivers. Secret behind it is the type of
rice that is used when making the pack. Also can be machine washed after taking
out the end stitching to remove rice.
