Includes 16 purple candles. Each candle is 2.5 inches tall. These candles would work great on a birthday cake, assuming that the person in question is no older than 16. If they’re older than 16 you can either buy more candles or hope that no one will notice. Does anyone actually count the number of candles there are on a cake? I don’t, but now that I think about it, I’m sure that there are people that do.
