Bring Back the Old One
I don't know why Mac decided to change this product?!?! This was my go to product for my eyebrows. I would draw in my eyebrows everyday using this pencil, or use it here and there when needed. It was a PERFECT pencil. I have blonde hair, shave my face, including my eyebrows. I do have my eyebro...

I really liked this but...
I really liked this eye pencil. I got the color Fling and it went well with my blue eyes, light mainly cool skin, and dark blonde hair. It goes on easily and looks great. That said, first problem was that it only lasted me a month, and I did not even use it every day. Second problem is that it breaks very easily, which of course tends to make it not last as long as other pencils. It was great for traveling, very small to carry in a purse or makeup bag in a suitcase. I may buy it again or may not. I would like to find a similar color in a brand that does not break and lasts longer than this.
Not worth the cost

Comments about SPIKED
I had their older version of this eye brow pencil and loved it. It had a thicker pencil and lasted quite awhile and was worth the price. They discontinued it and I was forced to buy the new "slim" pencil for more money (and less product!). The salesgirl said it was improved to draw more like a hair on the brow but it was a smaller tube and I would go through it faster. She wasn't kidding! I also have to raise it carefully, not exposing too much tip, because it's so much more breakable. This means I use up what's exposed and have to raise it again and again, at least 3-4 times when applying it to my brow. I will not buy this overly expensive piece of garbage ever again. I'll find another brand.
This is my favorite brow pencil.
It gives me a brow where I have none because of a scar

Comments about SPIKED
GREAT to mimic fine and precise hairs to make a natural look. NOT so great with durability as the product is sooo thin that it very prone to breaking. Necessary to only twist out a small amount, for a longer point of the product will break. Very long wearing.
Disappointed

Comments about STUD
I love Mac products and the eyebrow pencil was my favorite until I purchased the 1MM pencil on May 8th and on May 10th Mother's Day it was all gone! Every time I used it it would just break. I came to see if I was doing something wrong… but I wasn't I had it at just right and it still crumbled.
