Once you own a YUYU, the worlds first long hot water bottle, youll never go back to an ordinary bottle. The unique YUYU is nearly 3ft long, so when you curl up in bed it cocoons your whole body in warmth. Its made from softer rubber than traditional hot water bottles so its really flexible, & there are ingeniously-designed bubbles on the surface that trap air between the fabric & the bottle, so it stays warm from bedtime until morning. Not just designed for cold winters nights, it comes with an adjustable loop strap so you can wrap it around your shoulders, neck, back or abdomen to soothe aches & pains.
