4X Moonglow Iridescent Opalescent Federal Glass Stacking Coffee Cups Mugs These are 4 vintage Federal Glass moonglow mugs. These iridescent milk glass coffee mugs feature a D handle. This design was made during the 1950’s. Stunning mug that looks different in every light and angle due to the beautiful iridescent opal glow, termed moonglow. This set of four mugs is in excellent condition and clearly marked on the bottom, Heat Proof, F and the shield. Colors are true and vibrant. Any glare, white spots, and color shift gradations on the item are from my camera flash, reflectors, and reflective shiny surfaces. My items are shipped from Canada and I use Canada Post - we do not have a media rate or first class shipping as in the US. Canada Post charges by the size and weight of the items. When you receive your parcel, shipping costs do not reflect the 15% HST we have to pay in Nova Scotia on stamps. I do not ship on weekends or holidays as there is no mail service available at Canada Post on these days. Please remember that sometimes items are held up by your country's Customs which can extend shipping times. Always happy to combine items when possible to save you on postage. IF YOU PURCHASE MORE THAN ONE ITEM PLEASE WAIT UNTIL I SEND YOU A COMBINED SHIPPING INVOICE BEFORE PAYING. Combined shipping is based on the FINAL WEIGHT of your package - please email me the item numbers if you would like an exact rate for the items you are bidding on. Thanks.
