Yes, this marble will put your brain into a vice and into a complete tailspin thanks to its utter and complete AWESOMENESS!! This is a huge marble, and the pictures fail miserably to capture how incredible it is to look deep down into this one, with Eush's feathery fumeyness fluttering away into glass oblivion down in there. WOW!!! Seriously, it is killer and this marble is SO hard to let go of. It is topped off with some mind-blowing dot stacking on the backside....that really look like Glass STACKS. It is so cool!!
