The Yumbox is literally such an easy way to pack a lunch. It comes with four or six compartments to fill with things your kid loves. Two or three might be leftovers from last night, some fruit, a yogurt or string cheese, maybe a sweet treat—little servings of each for fun and easy variety. Plus, these are super durable and last a while—we had our last one for years and only got a new one because my daughter fell in love with a new pattern. They are made from BPA- and Phthalate-free, food-safe plastic. The lid is lined with molded silicone that engages with the inner tray to seal all the food wells individually so contents won't touch or leak outside the box.
