( F-Skirt) CABLE No issues to report on this DARK AQUA insulator. You want a upgrade ? This is it!!. It appears like it was intended to have the inside skirt threaded, it has the beginning of the threading but then that is it. It also has a nice piece of WHITE cullet in the dome glass, just where you want it. The glass is full of bubbles and bits of cullet...$55.00... plus postage. Buy with confidence! I ship USPS Priority Mail, with the buyer paying the actual shipping... Payment may be made by pay- pal or other forms. ---- I DO NOT SELL FAKE, PAINTED, STAINED or ALTERED INSULATORS. Don't wait for a sale, it's not going to happen. ** REMEMBER No Buyers premium to pay!!!! NO Bidding!!!!
