Even after two years, and countless smokes, Missouri Meerschaum's radically designed reverse calabash cob is still holding up after countless smokes. I regularly wipe the bowl out with unscented diaper wipes after each smoke, and is still quite the smoker. When I originally purchased it in the Summer of 2015, thought it a novelty and that it wouldn't hold up, but it's still going strong. Bravo MM. :clap:
