This is a set of two extremely popular and highly sought-after Jadeite (Jade Green) series Fire King mugs in excellent condition. These are the incredibly rare and heavy coffee mugs. They are stamped from the 1950s. Markings: OVEN Fire King WARE Heavy Mugs Weight: 460g and 453g, making them very heavy and rare. * Excellent condition. I acquired these about 20 years ago from an antique shop in the United States. I have not used them since purchasing them. They were displayed on a shelf. They are beautiful. I am selling them to organize my collection. [Appearance Check] They are in very beautiful condition. They have a shine and are in excellent condition. As they are vintage items, there may be slight manufacturing imperfections, whitening, and minor scratches. There is also some slight evidence of use. If you are concerned, please check the photos and consider purchasing. [Notes] I intend to ship promptly, but there may be some delays due to work commitments. Thank you for your understanding. I will prioritize the first person to purchase, even during Q&A. Most Fire King and other milk glass products were manufactured between the 1940s and 1970s. I am not a professional appraiser, so there may be oversights, but I appreciate your understanding. Please understand the quality of vintage items and make your purchase decision accordingly. #AmericanVintage #Glassware #MilkGlass #RestaurantWare #DHandle
