And in case you're wondering... it's about $11 at Sally's...
With micro's you can get probably 6 wicks per inch... In case you struggle with math...

that's 72 wicks per foot... or 36,000 wicks per box... Even if you're wicking dual coil that's 18,000 times... Even if you had to wick every other day (and you won't with rayon... but even if you did) that's about 98 years of wicks there... So, yeah... you're good for life...
