This is a 7′ x 12″ titanium sheet from Ti Goat that was used only a couple times as a chimney in my DIY stove. The sheet stores as a 12″ x 3″ roll, but then is converted to a 7′ x 3″ chimney when rolled out. Comes with a simple damper, 2 end rings, and 7 cable rings. Asking $60 plus actual shipping, or willing to trade for something interesting! Thinking knives, fishing gear, titanium gear, etc. of comparable value, but let me know what you got!
