This is one of Steve's incredible new electric aquarium marbles, with an AMAZING UV and fumed reef in the center, and then the fish swimming around it. And of course, those fish are AWESOME, especialy the killer piranha with awesome UV accents! Steve fumed that core and then loaded it with 4 or 5 different types of UV frit, so with a black light it is INCREDIBLE. As wild as the pics look, it's SOOOO much better in hand. I got to watch him make one of these at his home a few weeks ago, and these are some of the best aquarium style marbles that's ever been created! You will LOOOVE this marble.
