This is a good piece that belongs in an advanced foreign glass collection. The skirt is embossed ISOREX and on the reverse 2352. Note that it is 2352n 235.2 . Maybe no big deal unless you collect foreign glass. Color is a real dark teal. Condition is great. It is about 5 3/4" tall and weighs just over 3 lbs. Asking $100 plus shipping, which I think is about half price!
