Great design unimpressed with formulation
Overall, I was unimpressed with this product. The formulation was underwhelming and a bit drying, not harsh but also not the satin feel I prefer. The neutral color hardly showed up on my skin. It was not pigmented enough in my opinion, at least not for deeper tone skin. Maybe this may work on fair s...

Basically…..ripped off. ☹️
This pencil is a staple in my makeup kit. The new formula is soft and breaks easily and runs out wayyyyyyyyy too quickly. Terrible disappointment, #MacCosmetics terrible. Looking for a new brand. So sad.
So little product!

Comments about FLING
I purchased this Mac pro brow, definer, pencil in Fleming, and in the stylized color in late January of this year. I absolutely love the fine tip and the colors were great. I just use it to do some fine hair strokes. I started to use it this morning and found after a few hair strokes that there was no product left in the pencil. I cannot believe at the price of these pencils. They are so little product for the customer to use. I love the product, but I will not be paying 20+ dollars a pencil to only be able to use it for a few hair strokes for about a month. I'm devastated and very disappointed. because I use Mac make up foundation powder, eyeshadow and lipstick. I'm a very good customer I usually purchase everything at Ulta. Not sure what I am going to do. Otherwise to give you this review. Product is great as long as there are some in the pencil.
Waste of money
This has been a staple of mine for yearssss! Like well over a decade. This new pencil is teribble. Terrible quality, terrible value… I noticed the pencil was now super thin but figured it would make up for that in length. This pencil lasted a fraction of the time it normally does. Like it normally lasts over a year (because I wear makeup maybe once a week) but lasted barely over 2 months this time. Neverr again would I buy this. So sad. It was truly a staple.
Very disappointed
This was my favorite for many many years and whatever they did to the formula it breaks easy. Lots of product waste and seems like it just runs out quick. Very disappointing and looking for a new brand.
Don't get tricked!

Comments about SPIKED
I have used spiked eyebrow pencil by Mac for a little over 20 years…never has a Mac product only lasted 3 weeks, this 1mm version is a complete waste. So disappointing the old version is no longer available - this isn't close to matching it!
