This is my favorite bento box, even though I don't use it for food, lol. The chambers are a bit too small for an American food portion (lol) but if you're trying to eat well and in healthier portions, this is the right bento box for you quite possibly! Personally, I have another bento box I prefer to use, but this one also makes a perfect storage box for small things! It would be great for jewelry, but I use mine for holding stickers and pins.
