We attach great importance to quality and safety and try as far as possible to work only with high quality ingredients, primarily sourced within Europe. All products are safety tested and compliant with EU regulations. It is possible that in very rare cases allergic reactions occur in both humans and animals—please review the allergens listed under "More Info" and on the product packaging to be sure to avoid certain ingredients you have reacted to in the past. We also point out that you should not leave your pets and/or children alone with candles and keep them away from the fire to avoid accidents.
