Me and my wife use our old warmers everyday …they are part of out lifestyle! Out by our fire-pit we have a microwave …. yes a wee hillbilly but awesome ….. and we heat and re-heat our warmers as we sit in the cold here in Minnesota. We are old circus folks so our parts are a bit creaky. Old circus folks are called “Kinkers” as they are always trying to work the kinks out. Your Warmers so help sooth our joints!
