Using your Audo Duca Candle Holder is easy. First, place a candle with a diameter of up to 7/8' into the holder. As the candle burns down, you can adjust the height of the holder. Just turn the small screw on the side of the design. If you want it taller, turn the screw to extend the telescopic stick; if shorter, turn it the other way. When it comes to maintenance, use a soft, dry cloth to clean the brass part regularly. For the rattan, avoid getting it wet. If there's a little dust, you can gently brush it off. And remember, this item comes with a 30 - day return policy, so if you're not satisfied, you can send it back.
