For sale I offer this 145 B insulator. The colouration of this piece is blue with sweet amber swirls here, there, n everywhere giving this piece a super green/blue 2 tone effect when backlit in a proper case. I have backlit this with an aquarium light so it doesn't display the colours the best. VVNM to mint cond and ready for your case! $20 gets this badboy to your house in USA/Canada.
