Greetings from Montana! I am looking for a hot water bottle (the rubber old fashioned kind) shaped like a horseshoe. You know like the kind of pillow you can get for traveling and the buckwheat things you can get for use on the neck that you microwave and it stays warm for one hour. Our regular hot water bottle when filled with hot water stays warm for 8 hours and I seem not to be able to find a shaped one. Anyone ever seen, heard of where to find one of these?
