Using these candle holders is a breeze. Simply place your candles in the candle bowls and enjoy the warm, inviting glow they create. When choosing candles, make sure they fit well in the bowls. As for maintenance, wipe the holders gently with a soft, dry cloth regularly to keep them shiny. Avoid using abrasive cleaners as they might scratch the metal surface. And remember, only the holders are included, so you'll need to get your own candles to complete the look.
