Klasyczny korek do butli próżniowej (przed 2002) | 1 kwarta do 2 kwart

My old thermos finally seals properly again, and the temperature holds all day now. It was a perfect drop-in replacement for the worn-out one, and I didn't have to wrestle with it to get a snug fit.

The fit is perfect for my pre-2002 bottle, and the seal is snug enough that I can tip it upside down without a single drip. It took about two seconds to push in and it’s holding my coffee hot for hours like it did back in the day.

My old bottle wasn’t holding heat anymore, and this stopper made it seal up tight again—the fit is precise for the pre-2002 model. Even after a few hours, my coffee’s still hot enough to enjoy.
