Using these candle holders is a breeze. Just place your preferred Nexis LED Candles, HD8, or HD12 Liquid Candles inside the holders. Since the candles are not included, make sure to buy them separately. When choosing a location, pick a flat and stable surface to prevent the holders from tipping over. Avoid placing them near flammable materials if you're using real candles. To keep these holders looking their best, clean them regularly with a soft, dry cloth. For stubborn stains, you can use a mild glass cleaner. This will help maintain their elegant appearance and ensure they last a long time.
