This insulator has the biggest bubbles of any piece I've ever had. There's 3 big bubbles all squishing against each other in the wire ridge area, one having some carbon-stuff in it. One bubble is an inch and a half.....the other two are close to an inch. A crazy piece. There's four or five chipped drip with associated bruise, and pinky nail inner skirt flake, but who cares........THE BUBBLES THE BUBBLES. 145, shipped
