Heavy Clear Glass Modernistic Vintage Candle Holders

Description

Lovely pair of candle holders.  Modern and classic at the same time.  Together they weigh two pounds.  Each is  3 1/2 inches high with a base of 2 /14 by 2 3/8".  There is a manufacturing flaw in one the the holders (see photo)  which I have frequently seen in glass manufactured in the 40s, 50s and 60s, but I cannot prove their age.
