Purchased this as a gift for a couple of salt loving friends - It is great and attractive! A note to purchasers: we had one vial of the salt arrive empty and it says no returns, if you contact the seller directly they will work with you. The seller send me a replacement vial (very quickly) and even sent a cool little salt dish along with it. Will definitely get this set for others (maybe even me) in the future.
