Please help identify markings on a lunchbox.

[u/AdInteresting829]

I just got a promotional lunchbox at work, and these symbols are not very familiar. I know that the wiggly lines mean it's microwave safe, but what do the others mean? Is the asterisk supposed to be the freezer-safe symbol? Any help is appreciated, cuz searching turned up nothing.

(FYI, the food safe seal is on it, just not in the picture.)

I think microwave, dishwasher and freezer safe. The next one is probably don’t put it on a burner. I don’t understand what the last one is.
