Lot 20 Prolon Vintage MCM Melmac Green Tea Cup Saucer Salad Dessert Plate Set. This is a great set for your camper or RV. This is a great vintage set that includes 6 salad/ dessert plates, 6 saucers, and 8 tea / coffee cups. The material is hard plastic, melamine. The entire set is in overall good condition. ***** the only flaw is one of the saucers rims is not shiny like the rest. Look at my last 2 photos to see. The plates are 6 inches across The saucers are 5.5 inches across The cups have an just about 4 inch opening The cups are just over 2 inches tall. Please feel free to ask me any questions. Thanks for stopping by :)
