Well these containers claim to be BPA- and phthalate-free. Good to know.
There are plenty of things that aren’t necessarily good for us. If we shut it all down there’d be no fast food, no alcohol, no tobacco, no gasoline engines, etc. I prefer to live life minimizing my risks, but not to the point of being a bit paranoid. That’s why I scoop it out onto a plate until there is so little left that I just nuke what’s there in the container and move on. Unless of course it’s something greasy as that tends to discolor the container which I don’t want because I like it bright, shiny, and clear after I wash it.
I also really want to know the answer to this, for the same reason. LnL said they nested, but really, a few of the smaller ones just happened to fit sorta inside a few of the bigger ones and that was all. I want same size nesting.
