CIRCUMSTANCES HAVE DICTATED THAT I HAVE NOT BEEN ABLE TO GO ON THE BEACH RECENTLY. WHEN I DO RETURN I HOPE IT IS A COLD DAY SO I HAVE ANOTHER EXCUSE TO USE MY BRILLIANT NEW ZIPPOHANDWARMER. I HAVE A COLD JOB AND SOMEONE AT WORK RECOMMENDED THEM....THEY ARE BRILLIANT. http://www.zippo.com/Products/handWarmer.aspx Started mine up 7 hours ago,still red hot and soothing my aching back. BEACH BUOY.
