A thermos that is, if nothing else, overrated. Colleagues bought similar thermoses from supermarkets and they do the same job. Simply, this one is more beautiful

Excellent, I highly recommend it. The only "downside" is that if you want to put it in bags, etc. without leaks, you will need to purchase the special lid (+10 euros) because the one it already has has a permanently open hole. If you buy it, there is no chance of leakage anywhere. It also keeps drinks cold for many hours, I use it for frozen ice cubes and they can stay without melting for about 7-8 hours without exaggeration. It is also very beautifully constructed
