Aka 'Space Mac', this is easily one of the sweetest marbles I have ever sold. So, sooooo hard to let go of, I LOVE this marble! Fumed tubes that really do resemble macaroni, ha haa, swirl around a black hole. Are they time capsules for transportation to other dimensions? Are they energy pods which are powering a mysterious city within? Nobody knows yet, and it is up to the eventual owner of this marble to figure it out! If that feature wasn't enough, there is an awesome space scene on the backside (or the frontside sometimes?), with a swirling galaxy and other star fields. SUCH an amazing marble!
