Rattray's Marlin Flake pipe tobacco is a dark flake composed of dark Virginia, jet Black Cavendish, and a hint of Perique. It's a tad darker in color and has a different aroma, but is otherwise similar to Rattray's Old Gowrie.
 
Rattray's Marlin Flake also is available in 50g and 100g tins on our Rattray's tobacco page here.
