Thank you for viewing! This is a handmade item. It may not be perfect, but I hope you will understand and consider purchasing it. This is a slightly larger size of an azuki bean heat pack. The cover can be microwaved. The cover is washable (hand wash or use a laundry net). Heat in the microwave for 40-90 seconds and apply to the area you want to warm. *Be careful as it can get too hot, so start with a shorter time and heat in 10-second increments if needed. This size can be used as a large eye pillow, or to warm larger areas such as the abdomen, back, shoulders, and neck. It's also great for warming your feet before bed! Large Size Size: Cover 24.5 x 15.5 cm Inner bag 23 x 14 cm Materials: Cover: Cotton linen (Lining: Cotton) Inner bag: Cotton Azuki bean amount: Approximately 280-300 grams (Hokkaido-grown) *Contains lavender (Please comment if you prefer without lavender) *This fabric has nep and cotton waste. *Size may vary slightly. Apply to areas where you want to promote blood circulation, such as the eyes, neck, shoulders, lower back, sacrum, abdomen, and soles of the feet. The gentle warmth of the azuki beans will soothe your fatigue. Can be used repeatedly about 200 times, but do not use continuously. Please allow at least 4 hours for the azuki beans to regain moisture before reuse. If it takes longer to heat up or the heat retention time becomes shorter, it's time to replace the azuki beans.
