A hot water bottle that heats up in 15 minutes and can keep warm for up to 19 hours. This is a set of 2, one used and one new. I love warm goods and impulsively bought these the other day. I used one, but I found that the hot water bottle that I heat in the microwave is more convenient for me, so I'm selling these. Selling them individually would be more expensive. The price for the set of 2 is a bargain. To reduce shipping costs, I will ship without the outer box. Thank you. - Heating time: 15 minutes - Heat retention time: Up to 19 hours - Power supply: AC100V 600W - Product name: FUWANPO - How to use: Reusable
