Using these candle holders is easy. First, place the chosen candle (Nexis LED, HD8, or HD12 Liquid) inside the holder. Then, put the Satin Crystal Nested Glass Lamp on top. When using LED candles, make sure they are properly charged or have fresh batteries. For liquid candles, follow the instructions on the candle for filling and lighting. Keep the candle holders away from flammable materials and out of reach of children and pets. To clean, use a soft, dry cloth to wipe the wood and glass parts. Avoid using harsh chemicals as they may damage the materials. With proper care, these candle holders will add a touch of elegance to your home for a long time.
