Review on 🕯️ 100 Piece Pre-Waxed Cotton Candle Wick Set, 3.5" with Cotton Core - Ideal for Candle Making, Candle DIY by Carla Anderson

These wicks have a cotton core. They emit very little, if any, soot and burn very cleanly. Zinc wicks give off a lot of soot. They can even start to stink, and I've read that they emit chemicals into the air that you naturally inhale while the candle is burning. Haven't used zinc core candle wicks in years and recently found this seller on Revain. I will order these again.
