What better way to warm up than a pretty hot water bottle. We love this Moon-shaped model in buckle fabric. Thanks to its shape, it can be put on very easily around the neck to relieve neck pain. It also duplicates work. Put in the freezer, it can relieve sores. This hot water bottle is so pretty, it can also be used as decoration. Use: 2 minutes maximum in the microwave, then you have to wait for it to cool completely before heating it again. * hot water bottle with flaxseed.
