Using these candle holders is a breeze. Simply place a tea light or votive candle in the glass holder and enjoy the warm glow. They also make great table centerpieces for weddings or events. You can even get creative and use them for a DIY succulent terrarium. When it comes to maintenance, just wipe the metal parts with a soft, dry cloth to keep them shiny. And remember, the set only includes the candle holders and glass votives, so you'll need to buy candles separately. Also, be careful when handling the glass parts to avoid breakage.
