This and the Genius Elevated marble (also just listed) were part of a set of 3 early marbles that I got from Yoshi back in 2010 when he was reeeeally starting to crush his amazing dot stacking tech (which would be heavily copied by other artists in later years to come). This set of 3 represented the pinnacle of technical marble design creation at the time and truly boggled the minds of all who saw them. My picture of the 3 marbles was featured in an issue of Flow magazine back then, highlighting Yoshi's emergence as one of the world's greatest marble artists. I kept the largest of the 3 marbles and eventually sold these 2 to a collector. Those marbles sat tucked away in a case for the past 15 or so years, and now I have them back, ready to move them into a new deserving collection(s). This one is wildly awesome, with some seriously killer dotstacking moves inside and out. Take a close look and you'll see what I mean, VERY cool glass!! It is incredibly hard not to add this one back into the collection, trust me. This is a VERY special piece of Kondo history, don't miss it! Signed 'YK 10'.
