I ordered a bunch of sea salts some time back and have just now got around to opening them, as I was using up an old supply. The ones I bought a long time ago were VERY finely milled, almost like dust, and I used them in the shower. The new bags that I got have very big chunks in them compared to what I'm used to, almost like little pebbles. I read the online description and it's still the same, so has something changed? Is this okay? I want to use them for body wraps (don't have a tub) and am not sure how well their properties will absorb into the skin with this more solid, chunky texture.
