Review on ☕ Mingcai 27 Ounce Double Wall Stainless Steel Vacuum Bottle - Travel Mug for Hot Coffee, Wide Mouth Insulated Thermos Cup by Pamela Mcgee

I've been thinking about buying a nice thermos in winter to drink hot water anytime, anywhere, but I didn't expect it to take less than ten days to to buy this thermos, and the neck of the cup began to turn black. I accidentally saw the news about thermoses on TV. I think it's better if more people know this common sense. The news reports that some illegal manufacturers are using scrap metal to make thermos flasks, causing the level of heavy metals in the water to exceed the norm. If prolonged use causes cancer, the program will also teach us how to check the quality of the thermos at home. You can check this online before buying a thermos. I think this is a very important thing for the health of you and your family. I don't know why, I can't comment on the photo of the thermos changing color. I don't dare to continue using this thermos flask.
