I put a hangtag on my wickless candles instead of a label on the bottom of the jar. In testing, the label got to hot and would come off. CAUTION: Use only with a UL approved electric candle warmer on a stable heat-resistant surface. Do not cover, add water or warm on stove. Remove lid and all labels before use. Wax and container can get very hot; do not touch or move container or warmer until completely cooled. Contains fragrance oils that can be toxic if ingested. Keep candle, cord, and unit out of reach of children and pets. Do not pour wax down the drain because it can clog pipes. Never leave melting candle unattended.
