IDG Cup/Saucer/Lid Blue and White 4-3piece sets

You are bidding on 4 sets of International Design Group Coffee/Chocolate Mugs. They come with mug, saucer and lid. You get 4 mugs,4 saucers and 4 lids. T are no cracks or chips on them at all. I've had them on a shelf for a few years ,found at a sale. Don't know how old they are or much about them. I was told IDG stands for International Design Group. I really don't know for sure. Also I have an extra setting I will give to you if you bid on them. It has some bubbles on the saucer. So I don't want to charge for that set.
