Introducing the luxury YuYu Chelsea Hot Water Bottle by Richard Yu. This bottle is so much longer than the standard square hot water bottle to keep you toasty and warm. It can also be filled up with cold water to keep your body cool. This bottle requires less than a kettle to fill up (less than 1 litre), and features cleverly designed bumps on the surface of the bottle that traps air within the fabric making it blissfully hot or cold for several hours. The YuYu Bottle is made from the finest Grade A Sri Lankan natural, biodegradable rubber. The cover comes in a potash grey colourway, and is decorated with 22 hand-stitched mother of pearl buttons, in a Grade A 100% Inner Mongolian cashmere material which is renowned for being the softest cashmere in the world. Please note this Cashmere cover does not include the extendable strap feature because of its delicate material. Hand wash only, dry on flat surface.
