This and the Million Volts 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 amazing, but is extra special in that it includes some light touches of that green glass that gave Yoshi so many troubles that he eventually stopped using it. It's a beautiful color and looks amazing as always in this special marble! I love the opal sitting on top of there a well. This is a VERY special piece of Kondo history, don't miss it! Signed 'YK 10'.
