An oh-so-contemporary way of providing warmth and comfort? Introducing YuYu's long hot water bottle! The bottle is made from the finest grade A Sri Lankan natural rubber while the cover is crafted from luxe merino wool and grade A inner Mongolian cashmere ( known as the softest cashmere in the world!). It can be filled with less than a kettle of water and will also stay blissfully warm for up to 4-6 hours. We love how the mother-of-pearl buttons add an oh-so-elegant charm.
