So I'm looking at the website and it looks like all the candles with rings in them are taller and have "A ring in every candle" on the side. Mine looks exactly like this one. This one says it does not have a ring. Am I right to assume there's not a ring in there and I can be smug in the knowledge that I chose not to burn the whole damned thing?
