Oooh man, I love it when Ryan and Kaj get together!! They create some of the greatest and most complex and beautiful collabs around. This one is wicked sweet, with some of Ryan's stained glass milli worked into the design with Kaj's millie, which is then wrapped over a wildly bright UV core and twisted on the bottom. This marble is like magnificent painting with glass, so incredibly beautiful in hand, soooo much better than the pics! Just check out the complexity of this design. Flat out brilliant glass, and that core is CRAZY bright with the black light on it! Killing it here, don't miss this one, and at a GREAT price! Comes tucked in a sweet custom Ryan Teurfs wooden box along with a custom wooden stand.
