For transportation of hot tea to work I have this vacuum flask first ordered in the color lavender. Thanks to Amazon these delivery was just 2 days here. However, the flask is currently unprotected in a package and is only surrounded by some Knautschpapier. So the first bottle was also dented promptly in lavender. However, the replacement was, in spite of identical packaging, intact.
Due to the absolute satisfaction (details follow) we have this bottle in aquamarine color a few days later bought for our daughter, which also entrains tea to work.
Hot tea is for 4-5 hours still so hot that you can burn your lips in this bottle. When you open the bottle, it evaporated as from a chimney. After 6-8 hours, the drink is still very warm, almost hot, and after more than 8 hours, the heat sinks of lukewarm gene cold.
The bottle itself remains absolutely cold outside. I have the bottle and sealed before the first transport with water. Then I laid it in the sink and found two hours later on the head. 100% leak-proof !!
I am absolutely delighted.
If you fill the hot tea in the cups, there is one little problem. The cup is made of metal and is instantly hot. It is in danger of burning your fingers. When the but knows and is cautious, then everything is fine.
Full recommendation, anytime !!
