It's a coarse salt, as mentioned.

But also it doesn't have additives like table salt (e.g. iodine and anti-caking agents). Iodine at least has a definite flavor.

It's also very consistently made (though not between manufacturers) unlike some sea salts, and relatively inexpensive so it's the go-to kitchen salt (as against finishing salt) for a lot of cooks; you know what you get in a pinch every time.
