I hope you're having a great day :-)
So like the rest of the female population, I am indeed a MAC fiend! My obsession only started within the past year, but I've since moved near to a branch and I'm clearly obsessed.
This was another re-purchase and something I use pretty much every day without fail.
I went through a phase of having really dark, defined brows but I realised they were probably scaring people off so I ditched them in favour of a more natural look.
This is almost exactly the same colour as my brows! It's a self-sharpening style meaning you just twist it up to get the pencil and you don't have to carry a sharpener around.
It takes me about 30 seconds to fill in my brows using this. I literally just colour them in, it's so easy - and it looks so natural.
The only issue I have with this is - because the nib of the pencil is so thin - it ALWAYS snaps off! It's so frustrating, because it's quite expensive and I normally wouldn't mind but when it snaps off it wastes so much product.
I'm on the hunt for a decent dupe for this but I haven't found anything so far. The closest I've found is a brow product only available in the States - Maybelline Define a Brow! Grr. Let me know if you have the same problem :-(
