We've tried every kind of salt imaginable for a variety of cooking.  This salt is excellent on popcorn and veggies.  It is so fine that it gives you all of the flavor without that crunch.  A little goes a long way so be careful when pouring from the container.  About the container... Put it in something else if you can.  Just remember - those cute theater shakers rust to beat the band.  If you are going to use them - unscrew the lid when finished and cover the container with a baggie - then screw the lid back on.  Keeps the salt fresh and dry and helps the container last longer.  Just my opinion of course.
