This makes me think of that Art from Monsters University. Anyway, yours for £7 with free click & collect or add on £3.95 for delivery. Cheapest one of these neck hot water bottles I could see. If not, let me know.
You can get it in charcoal, pink, and grey too. Perfect for keeping your warm and cosy this winter, this neck wrap is soft and stylish. Boasting a simple design this wrap fits around your neck perfectly to give you a supported and comfortable feeling. Matching Teddy long hot water bottles and regular hot water bottles are also available.
