Our square bags measure about 9 1/2" x 9 1/2". They work
great for warming or cooling body parts. Place them on your
back as you lean back in your chair. This will help with the
lower back pains. Heat them up and place them in your bed
moments before you jump in...you'll love your side of the
heated bed!! Warming pillow works great for those cold drives
to work, or just warm it up and sit with it while at work.
