I am crazy about all of your salts. But, I honestly haven't opened this package because once I do, I'll have an open bag of salt in the humid summer. My suggestion - lose the box. Find a heavier gauge plastic bag that is resealable. Print all of your good info right on the bag. The last thing anyone wants to do in the middle of cooking is fumble with a box and then bag that doesn't seal. Sorry, I would just like the quality of your packaging to match the quality of your amazing salts.
I bought this a number of other items for a friend for Christmas. She loved it!
