ECO 4 6" Pretabbed Cotton Candle Wick
Choose a Variant

Product Update:
You may see some variation in the wax coating on the wick due to different coating processes. The variance of the wax coating on the wick has no impact on the burn of the candle.

About the ECO Series
ECO wick is constructed from natural flat cotton threads interwoven with paper threads that produce a rigid structure for easy pouring. The consistent flame and slight curl of ECO wicks work well with natural waxes and ensures an even burn.

ECO wicks are lead and zinc free.

For help choosing the right wick for your candle, visit our wick guide.

Conveniently secure your wicks with Wick Stickers (large) or Wick Stickers Pro.

My fav wick!

These wicks have always been spot on for me. They perform great in IGI 6006. Unfortunately, the CS recs are not even close on anything I try, but this wick has helped me in multiple containers.

Annoyed I bought so many of these

I bought a lot of the 8oz mason jars and was excited to see that they had recommended wick sizes so I thought good thing I can just buy a lot of these and be good but I tried it and had extreme tunneling and a lot of extra wicks, the wick was fine but the sizing recomendation was off

Hi Riley,

Thanks so much for your review. We’re sorry to hear that you may be experiencing some difficulty wicking your containers. While our wicking recommendations offer a solid starting point, because each maker has their own unique process, depending on the results of your burn tests you may need to wick up or down from our suggestions. We’d love to hear more about your process so we can help! Someone from our Support team will be reaching out via email to troubleshoot alongside you.

I bought these for my 8 oz Mason jars that I had bought from here, and the wicks were recommended to use. But they tunneled still.

It is a good wick, regardless of other reviews


I am not a bot, I am not trying to get candle science more sales but I've used this wick thousands of times, and am ordering another 1000 right now. For those people claiming tunneling or did not burn all the way. It's probably your wax or combination of wax. Personally I've worked out a formula that works perfectly for these wicks so don't blame the wick, it works fine. I just think the reviews on this product are not justified. It will work if you are capable of reading your candle and understanding that adjustments may be necessary.

No tunneling, but...

I've used these wicks in the apothecary jars for over a year now. I've rarely had any issues with tunnelingor them staying lit.. however, you HAVE to be on top of trimming them as they burn or you will 100% get black smoke, mushrooming and the glass blackening. It's a little frustrating at times when customers complain about this. Especially when you advertise correct wick care.

As expected, but CS needs to work on appropriate shipping costs

As the title says. Love my eco wicks, but CS is GOUGING on appropriate shipping costs.

Suggested wick, but doesn't work

I was using the LX-18 wick with the medium straight sided twist top jar and IGI 6006 wax blend. The flame was great and created a full melt pool, but there was a lot of mushrooming. I switched to this suggested ECO 4, but the first burn is barely staying lit and is producing a very small melt pool and is already showing signs of tunneling within 30 minutes of burn time.

Doesn't work with the jar

I bought these as one of the recommended wicks suggested for the straight sided medium jars. I'm doing my first test burn today and it looks like it's only burning a small radius in the center of the candle. In the past I've used a different wick and never had this issue.

These wicks are absolutely the worst wicks I’ve ever used. I should have known by how cheap they were and already rated badly. My candle was lit for five minutes before the wick tunneled my candle and would no longer light. I’m so upset I bought 100 wicks and have candles to make for my customers. Do not buy these!!!
