I bought this for my kindergartener who would be having lunch at school for the first time. I do find more snack-like type foods stay batter as opposed to foods that can get soft and mushy because they are not being kept cold. It is a little heavy for a young child, but it fits in easily in the Bentgo zipper lunchbox. He has had no trouble opening and shutting it on his own.

My 7 years old loves this lunch box !! The bentgo kids leak proof lunch box & water is amazing !! Such a life saver !! Best of all it's leak-proof ! It's also dish washer safe ! Very durable as well ! There also bigger lunch boxes from Bentgo as well ! Must have lunch box !!
