This is an eco-friendly hand warmer that can be used over 200 times. The natural steam and weight of the adzuki beans gently warm your cold neck and stomach. It provides a warmth similar to a steamed towel, like you'd experience at a beauty salon. Made with 100% pure adzuki beans, with no additives. Approximately 400g of beans are used. The adzuki beans are divided into five pockets, allowing it to fit comfortably against your body and thoroughly warm from the back of your neck to your shoulders. Ideal for relieving stiff shoulders, which can be a year-round problem, and for warming the abdomen to alleviate menstrual cramps and stomachaches. Also suitable for those with sensitivity to cold, for promoting warmth, for better sleep, and as a substitute for a hot water bottle. In summer or during a fever, you can cool it in the refrigerator and use it as an ice pack. It's also perfect for spot-warming areas like shoulders chilled by air conditioning or stomachs fatigued from eating cold foods. ◇How to Use the Adzuki Bean Hand Warmer◇ Heat it in a household microwave for about 50 seconds. If it's not warm enough, add 10 seconds at a time until it reaches your desired warmth, then place it on your neck or stomach and relax. The warmth is said to last for about 20 minutes. After microwaving, wait at least 4 hours before reheating. This is not meant to be carried around, so please enjoy the benefits of this hand warmer at home or in the office. ◇About Materials, etc.◇ Size: Approximately 42cm x 11cm American cotton The light gray fabric features a delicate striped pattern in white, creating a simple yet refined impression. I believe this design can be used by people of all ages and genders. The smooth texture makes it suitable for use throughout the year. Because it's filled with plenty of adzuki beans, it cannot be washed. No smokers or pets. While I create these with care, they are handmade by an amateur using a home sewing machine.
