Thank you for viewing! I started making this after seeing it used in an obstetrics and gynecology clinic. It was used to warm the mammary glands by placing it on the chest, warm the area around the uterus, and warm the eyes of sleep-deprived new mothers. The moderate weight is comfortable, and I fall asleep immediately. It's also a great gift. Heat it in a 500W microwave for about 20-30 seconds, then adjust it to your preferred temperature. The warmth lasts for about 20 minutes. For sleepless nights... For tired eyes from smartphones... I listen to YouTube while using it on my eyes, or I put it on the back of my neck on cold nights and fall asleep. Made with 110g of Hokkaido-grown adzuki beans and a pinch of coarse salt. A little rosemary from the garden is included. You'll be healed by the scent, like being in a forest. Can be used 200 times. Please be careful of burns from overheating. If using it continuously, let it cool down first. Size (when in the cover) Width: Approximately 8.5 cm Length: Approximately 19 cm Please refrain from purchasing if you are overly concerned about details. Please understand that this is handmade. If you purchase 2 or more, the price will be 450 yen each. Due to rising material costs, I cannot lower the price any further. I'm sorry.
