Plastic boxes

I'm after your help again! We have a number of children bringing in snacks in plastic boxes. They enjoy their snack at break time and then leave the pot on the table and forget all about it! These boxes are often not named and we are struggling to return them to their owners. As you know, at the moment we cannot use our normal lost property boxes. It would really help us if you could ensure that any boxes your child brings in is clearly named. Thank you!
