Jess Mae ECO 10 candle wicks are pre-tabbed and pre-waxed cotton wicks with a paper-core filament, designed for container candle making and wick testing. Each wick comes ready to use with a metal sustainer tab for consistent placement and faster builds. Because burn performance changes with wax type, fragrance load, dye/additives, and jar diameter, we recommend running test burns before producing a full batch. Trim wick to 1/4 inch before each burn and test in a draft-free area for the most reliable results. Remember Always test burn your candles after curing at least overnight. Never leave burning candles unattended.
