Review on Thermos universal for food and drinks with a double stopper 1,8l Arktika 205-1800 by Mateusz Swierczynski ᠌

After reading numerous rave reviews for the "Arctic" brand, I decided to purchase one of their 20-liter thermal bags. Also, after a month, I'd like to provide feedback. Identified a flaw. You can't unscrew the inner lid since it's stuck within the outer cork no matter how hard you try; instead, you have to unscrew the outer lid, press down on the inner lid, and unscrew it from below. The squeezing out of the cuff from below is plain to see. It appears that boiling water is responsible for this effect. Also, the main cover hardly shows that the protrusions in the inner cork are so slippery and uncomfortable that your fingers slide. One with a groove or notches would have been easier to hook. These are the most significant problems with the 205. In general, using a thermos was a pain for me.
