This marble is staggeringly gorgeous, and hails from 2008 which was one of the heyday periods for Travis when it comes to making Gravity Well marbles. Every one he made back then, he just nailed it, and this is one of the best of the best, coming out of my personal collection. The colors, the flow, the intricacy, everything - it's just a marvelous work of glass art. Guaranteed to enthrall!
