Hey guys, I was introduced to them via Peter Davis early on and invested in an early test batch of 10oz poured bars... The were... interesting, to say the least. Not sure if they continued to pour any more like that after the initial batch of 30. Some display wikid swirls, most had a 'divit' like a belly button... But NONE had serials like the above. About the thickness of a mobile phone... they stack pretty well
