I like my Monbento a lot. I bought the pocket cutlery from them and they fit well under the lid.

They come in an Original shape (maybe for you?) and Square (maybe for bf?). Microwaveable and dishwasher safe, just be careful with the interior lids. I always handwash the interior lids to be safe. Leakproof if you seal them up correctly.

I've had as much luck putting cut up lunch meat sandwiches in them as I have had with storing an onigiri lunch in them. Bento & co has some really cute sauce cups, separators, etc. if you need them, but Monbento sells things like that too that will match their boxes.

However, right now, directly from Monbento, you can get the square one with sauce cups and cutlery for only $27USD + shipping which is a good deal.
