I switched to these stainless steel containers when I was trying to get away from plastic tupperware for my kids’ snacks. These 3 containers are the perfect size for a variety of snacks. While I wouldn’t put them in my son’s lunch as they are difficult to open with little hands, they are perfect for my younger kids because I don’t want them to open their own snacks! The price is a little hard to swallow when traditional tupperware is so much cheaper. I admit I am much more vigilant about making sure I don’t lose these containers, which is sometimes an added stress I don’t need when I’m out-and-about with my little ones.
