Using these candle holders is a breeze. Simply place your Nexis LED Candles or HD8 Liquid Candle inside the holder. If you've got the optional Low Craftsman HC4105 or Craftsman HC4107 Wrought Iron Holders, combine them to create a more stylish setup. When handling, be careful not to drop the glass holders as they can break. To clean, use a soft, dry cloth to wipe the surface. Avoid using harsh chemicals as they may damage the finish of the holders. Keep them in a dry place when not in use to maintain their quality.
