I'm in my early 30s and this bag is just pure nostalgia!! It's not as bulky as you'd think. It's quite easy to use, just two zippers so that the entire bag opens fully and flat. The buttons and things on the front are just decorations. I was able to fit a couple sandwiches and some baggie of cut up veggies. If you put soda in your lunches, there's definitely space for soda. So cute and was hard to pass up!
