Oh man, you gotta see this one is hand, it flat out ROCKS!! This is easily my favorite Burton marble I've seen. The fuming is amazing, layer upon layer woven all over inside the marbles, with an INCREDIBLE opal navigating the glass within! And I looooooove that blue-green raked backside. There are very few modern era marbles from Ben out there, grab these while you can! Signed 'Burtoni 2013'.
