Decorate your jar candles with candle jar caps, candle caps, or candle lids to help your jar candles burn evenly while reducing candle soot and prevents candle flame flickering. Our candle lids can be used on our 16 oz jar or 26 oz jar candles. Jar caps are 3 3/16" diameter, and can be used on a jar with a maximum opening of 3 1/8."
