Canadian company Steeltainer, has a really terrific take on the classic Bento box.
Each side of the lid has a simple snap up/snap down clasp to really
keep the thing sealed. And yet it’s so easy, my four year-old doesn’t
have trouble at all; I definitely can’t say that about every Bento container I’ve tried.
I love that the smaller snack container has a steel divider that can be
repositioned, should you need more grapes than goldfish, or a 50-50
split. It also stays nicely sealed, thanks to
a little grippy green leak-proof rubber strip on the inside of the lid. Now at
first, it popped right out and I kind of freaked (oh my God! I broke it on the first use!) but as it turns out, there’s a little well around the perimeter of the lid and it pops right back in in a sec.
The containers themselves are elegantly simple and nicely designed, but you’ll find the for-the-trade website rather perfunctory; models
have sexy names like “SE-560 Deluxe Salad and Sandwich Container.” Good thing you can find them on Amazon. –Liz
