There are 4 pieces in this lunch set. The set is brand new and still sealed in it's original packaging. The first piece is is rectangle in shape and is great for holding crackers or vegetables in. The second piece is square and is made for holding a sandwich. The third piece is in the sandwich box, it is for holding a dip or a salad dressing. The last piece is a bowel. Perfect for a salad. The all seal tight with with flip down side locks, the all have them one on each side, so they are spill proof. They are made by Hana Cobi. We ended up with two sets and we simply do not need that many.
