It says Czechoslovakia on the stem of this beauty but it is easier to feel that to photograph. The marbled cut or molded glass is blue and clear and shows no dings. The stem screws into the point so not suitable for fine fabric. I can see it on a felt hat or a wool label.
3 1/4 inches long and in excellent vintage condition with free postage.
Art Deco, 1920's
