The weather is getting colder! How about a hot water bottle to save on heating costs? It will keep you warm not only at night, but also during the day just by placing it at your feet. Please note that there is no hot water bottle cover. This is a poly hot water bottle from Onoue Seisakusho, which sells many hot water bottles. The size is small, 2.3 liters (approx. 29 x 22 cm), and I think it's easy to use. This is a new, unused item, but there are some tears in the film during home storage. I have included photos of the areas that are noticeable at a glance. There may be other small damages besides the photos. I will wipe it clean with an alcohol sheet before shipping. We use the same one at home, and we can spend the night warm until morning. Safe anonymous shipping & shipping included No discounts To keep shipping costs to a minimum, the packaging may be simple. Thank you for your understanding. Thank you for your business.
