This wicks are amazing for tealights. I've tried the eco ones and they did not burn consistently. These CSN wicks perform great! They even burn clean using the new Golden Brands Tart and Melt wax - which said that the wax wasn't made to use as a candle, but they work perfect in tea lights! I've already burned a few tea lights with Very Vanilla scent. Anyway, I used to use these wicks with Ecosoya PB wax and it also worked perfect. I like these wicks so much that I'm tempted to try these for my container Candles, but Candle Science suggests only ECO wicks with GW 464.
