Neiman Marcus W Monogram Coffee Mug Set of 2 NWOT

2 New No tags Neiman Marcus W Monogram Coffee Mugs. Set of 2. These have been in bubble since purchased. No longer available. Shown in photo there is a tiny dot within the ceramic finish.The other looks to have a thin brownish line on it. This line may rub out not sure if it is in the glaze finish. These are dishwasher and microwave safe. I have had a dozen of these for at least 10 years and none have ever broken. Very nice quality!
