・Heat in a microwave oven at 500W for 30 seconds / 600W for about 20 seconds. Adjust it slightly so that it feels comfortable without being too hot.
・Be careful not to overheat, as it may burst, ignite, or burn.
Also, if you don't use it for a long time, you may get insects.
We recommend that you use it as regularly as possible.
・ Since the water in the red beans will be blown away, please wait at least 4 hours before using once warmed. Doing so may cause it to burst or burn.
・If you are concerned about dirt, wash by hand or put it in a net.
(The inner bag contains red beans and cannot be washed.)
Also, if you plan to store it for a long time, dry it well before storing it in a sealed bag.
・We recommend that you use the red bean pillow about 150~200 times. When the red beans run out of water and don't get warm, you're done.
