Thanks so much for this hack! I looked up the grinder after it was empty to figure out how to refill just to find it was designed to NOT be refillable! I was mad that the marketing tricked me into thinking I was buying something environmentally friendly but in reality it's worse than my regular shaker! Shame on Morton! Then I found your page and by softening the plastic, which I wouldn't have thought of, it worked like a charm! I had already bought the course grind salt by Morton which is right next to it on the grocery shelf, again tricking me into thinking it was refillable, so I was very happy! I'll be doing the same for the pepper! Yay
