The salt doesn't come in sachets/individual packets. It's basically one giant bag of salt. You can scoop the salt directly out of the bag into a neti pot but what I do is pour the salt into two jars that had salt in them previously (the Himalayan Institute 12 oz jars) and store the salt that way instead of keeping it in the bag.

I'm not exactly sure as I can't really weigh the Neilmed sachets that I have, but I would have thought they contain 2/3 grams of salt. Therefore, that being a reasonable assumption, then a 680g bag of this would render the equivalent of 226 to 340 sachets. But you'd need to weigh the contents of a neilmed sachet to be sure. Hope that helps
