For sale here are two great insulators. The first, being a MINT CONDITION CD 728 threadless. Also has nice amber in the dome, and skirt. Has the slight nibbling on the very edge of the sharp mold line, and that's it. This should be visible in the picture. The other insulator is a CD 145 B in a strange light aqua. It is mint also, with a nice milk/amber streak in it. You don't see the B's in this aqua that often. Asking 195 bucks, S&H paid.
