These glass hearts were made in the 1980s and early 1990s in molds in Czechoslovakia. The heart is a very light pink. Stringing it on pink string would bring out the color more. The heart is 8 mm from hole to hole and 8 mm and the widest point. The hole will accommodate a 0.5 mm cord. These are a sweet size for earrings or small charm. Price is for 10 beads.
