Using these MacKenzie - Childs Bands Dinner Candles is easy. Just place them on your dining table to create a warm and inviting atmosphere. Before lighting, always trim the wick to ¼' for a clean burn. You can enjoy the lovely luster they cast for up to 10 hours. But make sure not to burn them for more than 3 - 4 hours at a time. Let the candles cool down before relighting. Safety first! Never leave a burning candle alone. Keep it away from things that can catch fire, and make sure kids and pets can't reach it. Also, try to keep the candles out of drafts. Since these candles are handmade, each piece might look a bit different, which makes them even more special.
