The box seems to be airtight however the closure does not seem like it always closes tightly. That's why I gave 4 stars instead of 5.

Great lunchbox for my preschooler! It’s so easy to pack and fit in his little backpack. The food stays put and it’s easy to clean. Love it!

It’s perfect for my 4 year old! She’s able to open and close it without assistance and it fits all her snacks for preschool!

We love this lunch box. Because each compartment seals when you close the box, you can fill the box with sauce or dips as well.

So many compartments. I love them and hate them at the same time. Haha! Overall great lunch box, easy to open and close.

I use this for my 9 year old’s school lunch. It’s a great size and easy to clean. Very happy with it.

Happy with the product but super upset that it would have been 1/2 the price to purchase from Sam’s club vs the bentgo website.

Lunch box is awesome, but the plastic part that avoids leaks has defects. Instead of being smooth has like burn plastic marks.

Very sturdy and less to mess with when packing a lunch. It is all right there and divided out so no losing lids!!

I found the compartments for serving too small and it is hard for younger kids to open without dumping. The lunchbox is spill proof.
