The product is a vintage McKEE GLASS CO. butter dish made in the 1950s. It is a rectangular-shaped dish with a lid, made of jadeite (SKOKIE) glass that glows in the dark due to the uranium content. It has a single compartment with two cups and is 6 inches long, 4.5 inches wide, and 3.5 inches tall. I am an experienced glass shipper so bid with confidence. These don’t come up very often, get yours now. Please see all pics of the flea bites on the rim, they are part of this auctions description. This piece has sat in my collection for the last several years without use. It is in AS FOUND condition. Still has LOTS of life left, add her to your collection today!
