Art Deco blue opaline cups

Tender duo of cups in blue sky opaline art deco style. A classic of the twentieth century in a color today quite rare. In good condition. Old model to collect or associate with other vintage opalines. At the edge and in the mass, the glass has small imperfections due to the vintage manufacturing method. Small manufacturing tasks on the edge of a cup. Neat and secure shipping. If necessary please tell me your favorite relay point.
