Thank you for viewing. This is a multi-pillow containing adzuki beans from deux C, which can be heated in a microwave and reused. The beans contain a lot of moisture, and when heated in the microwave, the moisture turns into steam and warms each part of your body. Because the adzuki beans absorb moisture from the air, you can use it repeatedly. The adzuki bean grains gently conform to your body, and the moderate weight and warmth gently warm and soothe your shoulders, neck, abdomen, etc. The cover can be removed and washed, making it hygienic. There are no instructions. [How to Use] Heat in a microwave (500W) for about 50 seconds, check the temperature, and then warm your neck, shoulders, etc. for about 15 minutes.
