It's perfect for warming the abdomen and lower back when you have a stomachache or menstrual cramps. In our house, it's an indispensable item because we always warm our children's stomachs with the azuki bean warmer when they complain of stomachaches. The scent of the azuki beans will disappear with repeated use, but the warming effect lasts, so it can be used for 2-3 years. The cover can be removed and washed.
