I have the kind filled with field corn. There is a slight odor when they are heated. The maker did put cinammon sticks in which helped for a while. The odor isn't horrible and I still use them for aches or chills. I even use them at work in the winter when they keep the thermostat too low for me. Just place it in my lap to warm my hands on. But I'd love something with no odor. I'm curious, does the rice have an odor? |
