To ensure your reed diffuser or candle does not cause harm to children or pets, please ensure they are put in a responsible place, so they are not knocked over or within reach of children or pets. To ensure your candles burn safely, please ensure they are not in a draughty position as this gives the safest burning performance. All the wax that we use in our candle products is refined to the highest possible standards of purity and is not hazardous to health, nor does it pose any adverse effects to the environment. Our wicks are made from cotton.
