Great little thermos!!

Great little thermos for carrying hot or cold food to work! Don't lose the seal when washing or it's useless. And, it comes off easily. Great price for a really good thermos!!

Great Little Thermos

This is the perfect size for lunches. I fill it with Mac and Cheese for my granddaughter. Yes, she eats it every day. The mouth is wide, making it easy to clean. It is also dishwasher safe. I use it all the time. Great price too. I have several of them. Hot or cold it can handle it.
