These rich scented 10oz vintage bowl candles are made of 100% American Soybean wax for an intense fragrance that quickly fills a room; Soybean wax is clean burning and lead free. The designer candles containing decorative dried or silk material require special attention; in some of the decorative candles the wick is placed off center on purpose; all of the wax is not meant to melt in these candles. Refrigerate candles to prolong burning time; to maintain color and fragrance, store candles in a dark, cool, covered container.
