I live in Florida and the humidity is no joke here. I have had brown sugar and salt turn into giant boulders within weeks of opening a new package. This pop container is truly the BEST invention ever!! I love that it comes with a ring for brown sugar. I honestly didn't know you had to soak the ring before you use it as well. Now my brown sugar stays so soft and moist. It sounds silly but it really is like Christmas each time I go to use it now. It's excited to not waste sugar or salt any longer.
