Eco-friendly and long-lasting warm mofco hot water bottle, with approximately 8 hours of heat retention. I received this at a company event, but as I have a young child, it's not suitable for use in my home, so I'm putting it up for sale. ^_^ - Brand: mofco - Size: Approximately 23 x 33cm - Usage Time: Approximately 8 hours - Included: Instruction manual Thank you for looking.
