I was searching for something like this in Belgium, but I couldn't find it. That's why I ordered this salad box at Amazon.
I had my doubts, because the picture didn't really tell much. But once I opened the package and saw the box, I was so excited! It's exactly what I was looking for.
Not too big, so it can fit in my backpack. Not too small, so it can contain enough.
You can put salad in the box, and in the compartments above you can put small things to put in your salad later (like cheese, tomatoes, ...).
There's also a small container for dressing, which is sooo clever!
Also important: it's waterproof (I tested it).
It also has plastic cutlery, but I think I'll just use oldfashion cutlery (because I just don't like to eat with plastic cutlery).
I totally love this salad box, and I would recommend it to everybody!
