This solid rod implosion measures 1.33 inches in diameter. I am finally getting these down without any air trap. I have been making several mill canes tge past few months trying to hone my craft in. This one has several of my new ones that all have matching color schemes such as Royal Jelly, telemagenta, amethyst purple and green slime. The center coin is my favorite right now a closeted of canes I bundled together. Comes with 3D printed marble stand and free shipping on web site orders.
