I don't use any other lunch bagMy 5th grader picked this lynch bag because of its marble color. The design is nice. She is able to place her bento box inside along with other items.I am a college-educated adult who was nervous to recently start a new job. I would need to pack my lunch because my new office wasn’t really close to much take-out. My teenage kids asked if they could pick out my lunchbox, and in a moment of weakness, I said okay. They were super-supportive when I was looking to switch jobs, so I was happy they were invested. And then the lunchbox arrived. No one has mistaken it for theirs at work. And TBH, you can’t help but smile when you see it. I *did* take a star off because it’s smaller than they/I thought it would be, but in the whole, it was a real conversation-starter at my new job ?GreatThe bentgo lunchbox fit perfect in this and I can put a thermos in there for her school lunchIt's a lot smaller then I thought it would be but it does insulateExactly what I wanted/needed.
