I’ve used two ECO 02 150mm Wick in 11 mm diameter jars and I’m really pleased with how they performed. Both times I got a nice, even melt pool after burning, which made my candles look professional and burn more completely.
These ECO wicks are easy to work with — they’re stiff enough to stay upright when pouring and they burn with a steady, consistent flame that helps the wax melt evenly rather than tunnelling or burning sideways.
What I especially liked is that they’re lead‑ and zinc‑free and made from natural cotton with paper woven through, so they feel like a cleaner and more eco‑friendly choice.
Another benefit I noticed is that they don’t produce a lot of soot or smoke, and they seem to burn cleaner overall compared to some other wicks I’ve tried.
For anyone making container candles, these wicks are reliable and deliver what you want — even melt pools and a stable flame — without fuss. Highly recommended!
