Looks a lot like Salon Coil cotton. But salon coil cotton is 3.29 for 45 feet.
Pretty much ALL of this "high-end" stuff is repackaged commodity fibers. Time is money - not everyone is willing to search out the perfect wick. Anyway, when you buy it, you're supporting a vibrant small-business economy built around vaping. I know that doesn't fly with everyone, but it works for me.
On a related note, I have 8 oz of what I hope will be next-level bamboo wicking material winging its way to me. I didn't buy more because I don't have room for it. And I paid almost as much in shipping as the fibers cost, which is next to nothing. Maybe I should name it "Panda Wick", review it on YouTube, and sell the crap out of it.
