I initially bought 4 and then was so impressed with them that I bought 4 more.
I use them for sandwiches, small baked items, and also for storing cheese and lunch meat.
The different colours mean that I can colour code which ones hold the cheese and which one holds the lunch meat.
I put them in the fridge, the freezer and the dish washer and they are just as good as the day that I got them.
I would highly recommend them.
Perfect for lunch bag and prevents the sandwich from getting squished , which often happens with sandwich ziplock bags.. when grilled it holds upto two sandwiches
