Yutanpo (hot water bottle) size (approximate measurements by amateur): Body: Width approx. 18cm, Length approx. 14.5cm Including cover: Width 24cm, Length 20cm Purchased about 2 years ago and used a few times. I didn't use it at all last year, and it has been stored at home, so I am selling it. The zipper closes. Instant purchase welcome! Thank you. #CitronBundleSalesHere
