CAO PIPES Simply put, meerschaum affords a unique smoking experience. Meerschaum is the most flavorful and beautiful pipe you can own. Meerschaum - one on the most porous substances found in nature - acts as a filter, absorbs tobacco tars and nicotine, and yields a most satisfying smoke. Meerschaum smokes cool and dry with a flavor unrivaled by another pipe. As it ages, meerschaum colors a rich honey-brown, improving both in appearance and taste. Meerschaum Pipes - with a minimum of proper care - will last for a lifetime. A CAO meerschaum is an investment in smoking pleasure.
