I got these mainly for keeping some cash, important cards, and other small valuables together in one place. They're a convenient size for things like passports, keys, cash, and smaller documents without taking up much room in a safe or drawer. The material feels thick and sturdy, and I like that you get two separate pouches so everything doesn't have to be stored together.
Obviously I'm not going to intentionally set them on fire to test the fire resistance, so I can't speak to how they'd perform in an actual house fire. I look at that more as an extra layer of protection than a replacement for a real fireproof safe. For organizing and adding some additional protection from water or heat, though, these seem well made and useful for the price.
