This is one of the coolest marbles ever, and you've gotta see it to believe it. It is based off the concept of the mobius strip, where you can wind around and around the twisted circle times infinity. It has blue/green/goldstone on one side of the strip, and yellow/orange/goldstone on the other side. It's fun to twist the marble around to see inside to the other side. Such a killer design, done so well, to the point that I have no idea how George did it, ha! You will love this marble when you see it in hand, guaranteed! Soooo hard to let go of.... Signed 'GMP 6'.
