This collab is different than any I've ever seen before, featuring a Hefe fumed flower tree floating in front of a Bo Howe fillacello. Great colors are seen throughout, and then that sweet opal cube is floating so perfectly over top of the fumed tree. You can sort of see in pics 3 and 4 that Hefe's fumed design is actually 3 separate fumed sections melded together, so cool! Hefe put the marble together using one of Bo's filla's, along with some of his dot stacking on the backside. Just a flat out NEAT marble - that fuming ROCKS!!
