Vintage Lomonosov Porcelain Tea Cups and Saucers Set Of Four. There is one chip on one saucer. The Saucers are 1" tall x 5 3/4" in diameter.
The cups are 2 1/4" tall x 4" in diameter and 4 3/4 in length. They have an 8oz capacity. The Cobalt Net pattern was started in 1945. I did pick a manufacturing date in specifics but do not know it.
