Review on 🍶 Thermos NCB Classic Stainless Steel 1.8L Thermal Flask by Ada Stasiak ᠌

The thermos is good, it may not keep all the declared 36 hours, but it is long enough. For frequent trips to nature, our family had enough of its capabilities and there are no complaints about the product in this part. However, after 5 years of constant use, the cork began to crumble. At first I did not understand what kind of whitish particles began to float in the tea from the thermos, and then I saw that the screw cap itself gradually began to collapse. So the company can and does give a 15-year warranty on heat-insulating properties, but this probably does not apply to cork. Will have to buy a new one.
