I received one of your candles as a gift. I lit the candle for no more than 4 hours as you can see from the amount that has burnt away. Thought nothing of it and the following morning myself, husband and 2 daughters woke up with black bits in our nose. We found this very strange. It was only when I went into the room where the candle had been lit and found the walls were covered in a black like film. The curtain which was white was now black and the white UPVV window is now covered in black too. This is a safety hazard and should be removed from sale straight away. I now have to buy a new curtain, clean the windows and re-paint the whole room all because of your candle. I expect a reply regarding this asap. I have photos available that I can send to you to show the candle and the damage.
