I have 3 of these containers that I did not get all at once. The first one I got because of the latch opening. My daughter's little fingers could open this! They are so well made; very sturdy. If you can find them in the different colors, get them. I had never seen them in clear until recently. Good for bento-ing and can hold a whole lunch meal once you get used to packing it. Use silicone cupcake molds to quarantine items if you need to. They're the right fit.
It does need a cooling pack but I got those at the $1 section of Target. I wish it came with a drink container but that's just me being picky. Also, beware that I might not fit your kid's lunch bag. I went through a couple of bags until I found one that this could squeeze through.
