"Perfect flask"
I bought the small thermos king flask for my husband, who drives a bus and he needs a flask that keeps drinks hot for a long time and as this keeps drinks hot for 12 hours and cold drinks cold for 24 hours as he is out at work for 12 hour days it sounded perfect , and it is ,He says it is great the best flask he as ever had,he also likes the shape of the drinking cup . and you can just unscrew the top a little and you can pour out a small amount and save the rest and it stay's hot, if you want a really good flask get this one you won't regret it
