I was on the hunt for a bento box to use for veggies, cheese and dip on the go, and this fit the bill for my needs. Yes, I am an adult proudly using a kid's lunch box! I like that the side clasps secure tightly and the size is not overwhelming unlike the other bento boxes.
The downside is that the two small containers do not have airtight seals, so while thick dips like hummus won't spill (the main lid keeps everything in place), liquids in a mini salad do seep out a little. Another small critique is that the clear plastic lids for the small containers scratched up on first wash using a scrub sponge. Otherwise, I am very pleased with the purchase and would recommend it.
