I have been using the glass jars for the past couple of years because I wanted to avoid the plastic used in deodorants. Pretty Frank's cardboard alternative is a hit in my book. It is sturdy and has been holding up to daily use. Its compact size is also convenient and helps me minimize the space I need in the bathroom, and on travel. The cost is more than I can get deodorant elsewhere, but I have gotten used to that already as I made a commitment to minimize my purchase of plastic wherever I can awhile ago.
