I ordered this for my husband because he enjoys a beer now and again on a hot day, but it gets warm before he finishes it. He has tried all kinds of koozies over the years, and even has another stainless steel one that works great. He likes this one even better, though, because it also works with bottles. Just pop in a cold one, screw the rim back on and those double-walls of stainless steel with a vacuum in between will keep it amazingly cold until you finish it off. The koozie doesn’t sweat on a humid day, fits the hand nicely, and cleans up like a breeze. It’s a summertime must-have! Disclaimer: I received this product at a discounted price in exchange for my unbiased and honest opinion of it.

I used this to seal in a marriage sand vase and its worked perfect. I can turn the vase upside down without it popping out. I wouldn't do it many times since it'll change the pattern of the sand as well as the sand might settle a bit. after a few months of the sand settling is when I did this. a few months later the sand has settled a little more. Might test drilling a hold and refilling the gap but we'll see.
