This solid rod implosion is 1.44 inches in diameter. It’s a new technique I am working on. I took the leftover ends of my colorful worms milli and put them in a sort of patchwork quilt type pattern. I’m loving making these right now. Still working on my technique so this one has a tiny bit of air trapped in a gap but not enough to bother the eye. In fact looks sort of cool. Full disclosure 😉👍 Free 3D printed marble stand included and free shipping on my web site.
