These devices aren't used much anymore, having been replaced by electronics. Back in the 1960's, if you had a stomach ache, or sore muscles, you would fill this thing with hot water, perhaps wrap it in a towel, hold it close, and go to bed. It was actually, quite soothing. This one, a Rexall Symbol, was never used, and it comes in its original green, white, and chartreuse box.
