This is a hot water bottle like the one in the photo. I bought it for emergencies and disasters, but I usually use an electric warmer in the winter, so I'm putting this up for sale. I've included the text information in the photos, so please use this information to help you decide whether to purchase. The size, measured from the top of the bag to the body of the bottle, is approximately 15cm wide and 25cm long. It will likely expand slightly when filled with hot water, so please use this as a reference. Although it is new and unused, please forgive any initial scratches. Please refrain from purchasing if you are sensitive to such things. It was originally placed in a transparent bag, and I will ship it as is in a Yu-Packet Plus box, as shown in the sixth photo. It is made of a soft material, so I will not wrap it in bubble wrap, so please be aware of this. Also, the part where you pour in the hot water is about 4cm thick and has a core, making it rigid. It wouldn't fit in the post slot for Yu-Packet Post (I sold a similar item before, but I had to change the shipping method from Yu-Packet Post to Yu-Packet Plus because it wouldn't fit in the envelope), so I will be using the Yu-Packet Plus box shipping method. Please understand. Shipping costs about 500 yen, so I cannot offer a significant price reduction like last time, so please understand.
