Mushroom Glass

Vintage plastic mushroom tumbler. It is in an unused condition and still in the package, made by Nasco, Inc. in Springfield, Tennessee. There is a paper insert, dated 1982, describing their care. The plastic has a slight textured finish and has gold mushrooms on one side. I cannot find any problems with the finish, including the decals. I do not know the capacity as it has not been used and did not want to put anything in to measure them. I have 6 available and priced individually. I need your zip code to calculate the postage.
