I use laptop lunch boxes and Love Them. I have about 8 boxes for the 3 kids to use for the week. They are plastic which is not a problem because I only pack cold foods. For warm lunches I use Mr.Bento. I love these for so many reasons. I always pack vegan for these and the kids are used to seeing lots of veg in the box. I'm keeping an eye on my special needs child that she doesn't get too heavy and these are so great for portion control. The boxes are easy to arrange and I pack up to 5 at a time so it's easy to load them up assembly line style. They are durable and the first sets I bought are still in good shape after 2+ years of almost daily use. They come with real silverware and lids for two of the 4 boxes. They include a dip container and depending on the style, a drink bottle too.
