The circular-tinned candle is an eco-friendly alternative for the candles you can find in the supermarket. This candle is eco-friendly as it is made of soy, making it non-toxic and it also burns cleaner than regular candles. Since this is made of soy, expect this candle to be biodegradable. Plus, buying these soy candles are also of big help to U.S. farmers as these are USA-made. Do note that this candle's tin is made in China.
