This works incredibly well. I had brown sugar that was like a solid rock and I had it in a sealed bag inside of a sealed container and it still somehow dried out. I tried a lot of at home "tricks" to soften it but they all have their caveats. Within 24 hours my brown sugar was super soft and usable after placing this in the bag. Only one star off because I ordered 3 (for myself and family) and one of them came chipped. I recommend trying this.
