I have struggled with brown sugar packages for years: ziplock closures clogged with sugar, shoving bread slices into the bag to prevent hardening, and ultimately putting the whole mess into a larger ziplock bag.  This OXO container easily solved that problem. It’s the perfect size for typical package of brown sugar AND the brown sugar keeper disc let’s me keep it fresh without using any more bread. Just soak it in water a few minutes and it’s ready.  It easily attaches to the top of the container and, Voila!
