From http://www.petrifiedwood.com/linksto.htmCu-Avana preserves the finest cigars with its humi-care system. Cu-Avana uses petrified wood slabs cut to order and polished at Stewart's Petrified Wood Shop to create the petridor! The petridor is a masterpiece that combines the ancient petrified wood of the Triassic Era and carefully selected mahogany woods accentuated with 24Kt. Gold-Brass hardware.
Too bad they're no longer in business it seems. I would like to see a photo of it.
