I was happy to see that Oxo came out with a pop container that was specifically for brown sugar.  I transferred my almost solid dark brown sugar from another oxo container and it softened right up! Two dowfalls of this product: (1) It only fits a 1 pound box of brown sugar and as a avid baker I typically have more than this on hand. (2) They top style of this pop container is slightly different from other oxo pop containers I own and in an organized pantry, you can notice that visually.  Otherwise, this product functions great and is a wonderful addition to the pop container family.
