Reddish-Brown sole bends measure about 2 feet by 4 feet, about 9 oz in thickness (3.6mm), and are so firm that our boys have invented brand new, never-before heard swear words when they try to roll these up for shipping.  Good for desk tops or, well, flooring.  Vegetable tanned, compressed in a hydraulic press.  We sell these to folks making furniture and/or armor.  $90 each, 48-state USA shipping included.
