A stellar example of the lack of quality control at WFG Co.

CD 121 Near Cornflower Blue with slight lavender tint also with a Yellow-olive streak above and around a portion of the pinhole. One small pot stone (a little larger than a pinhead) has a 2/3 pinkie nail halo just under the surface. Crude threads and surface annealing lines, typical of Denver glass. As for issues since leaving the factory, still a nice insulator and would make a nice addition to your Denver glass collection. Asking $200 plus shipping.
