I am sad to report that the container was not always that reliable. Sometimes it didn't remain shut. Also, I grew tired of washing such a small container, which is surprisingly not that easy to do. I just ended up bringing a bottle of mustard to keep at work.
Still, it could make a nice little container for something else, sans the spreader. Pill box? Ring box? A place to keep your kid's baby teeth? Really, does it need to have a practical use when it's so cute and small? Yasai!
