The OXO Smart Seal Glass container is a winner! The overall appearance is clean and modern. It doesn't leak, and the lid and seal do not become easily discolored (I used the container for some leftover spaghetti sauce, which always discolors non-glass). You can tell that the container is high-quality as the glass is thick and non-flimsy feeling. The latches on each side make a satisfying click, indicating the lid is locked. My new favorite food storage option. I'll have to buy a set!
