"Festiva Cobalt" design by Gunnar Cyren for Dansk International Designs. These candle holders are made of frosted blue glass with a swirling pattern and a central indentation to hold a tea light candle. The "Festiva" line, introduced in 1960, was known for its colorful, lacquered bowls and trays, and these candle holders are a part of that collection.
