Teenage Mutant Ninja Turtles Kids Sandwich Saver Bowl Lunchbox Container

So I bought this because it says 2 pack and 2 randomly selected characters. I have 2 boys and now one sandwich saver. The “2” must mean 1 lid and 1 bottom. Never would have paid $7 for this.

Design is great, but the tops don't stay in very well. I'm afraid the contents might fall out.
