I think this lunch box is cute, I bought it to match the backpack. It is well-made and sturdy. However, it is very large, and will likely not fit inside the backpack when it is full of books, snowpants, etc. I was a little surprised at how large it was when it arrived.
My son who is starting Kindergarten was so excited to see this lunch box with the animal on it. He likes it for the animal, I like it for the quality of LLBean!
These bags are great - I have 4 (one for each child). The three older ones use it for school and they are sturdy, clean easy and are a great size. I use the fourth one for my youngest to transport her bottles and formula - great size for that too. I would highly recommend.
This is my son's third critter lunch box. The first one he spilled milk in and the smell was awful and the second one he lost. It is a nice size with a handle and he likes the animals.
