A hot water bottle cover knitted from soft and comfortable 100% organic cotton yarn. The undyed, soft organic cotton feels like a stuffed animal. Finely stitched using lots of high quality organic cotton thread. In order to convert the heat emitted from the hot water bottle body into moderate warmth and maintain heat conduction, we layered two layers of Lilyan knit fabric to create an air layer in the center. It is reversible, so if you prefer a simple design or want to distinguish it from your family, you can use the flat side on the back. Please enjoy the two expressions. I would be happy if you could spend a warm night with the ``sleeper for your feet'' even on the coldest nights.

We hope that you can heal your daily fatigue with the comfort and warmth that only a hot water bottle can provide, as if you were taking a half-body bath. The included metal hot water bottle makes it very easy to reheat the cold water in the bottle over an open flame. Just heat it, cover it, put it in a hot water bottle cover, and put it in your futon before going to bed. The next day, when it cools down, you can heat it up again, and just by repeating that process, you will feel a very comfortable warmth every night. The soft warmth that is unique to ceramics is also hard to give up, so we recommend that you choose the hot water bottle according to your preference. The good thing about metal hot water bottles is that they are convenient and safe from breaking. Hot water bottles are recommended items that are kind to the earth and people. I would like people who have not used it yet to use it.
