Amazing and perfect brush to line eyes with e/s, wet or dry. Also very nice to use on brows (NARS brow brush is better for that purpose tho imo).

THIS IS MY FAVE MAC BRUSH! its so good! i dip it into the TINIEST amount of water pissible, then dip it into an eyeshadow and gently press a line across my lasline, and its perfect! just great! will repurchase FOREVER!

I love this brush for lining my eyes with eyeshadow, wet or dry. The brush still looks like it did when I first bought it. I use it all the time to make a thin line around my eyes with all kinds of eyeshadows, I'm liking this better than using a kohlpencil!

I have a HUGE collection of MAC brushes already so I decided to forego the brow/liner brush that I already have and love and "upgrade" to the legendary MAC 266.

I hate this brush! The hairs are stiff, prickly and scratchy. It doesn't pick up shadow well and it makes a very thick line - not pretty at all. I'm returning this first thing tomorrow! continued >>

One of the first high-end brushes I've bought. I like this a lot. It keeps it shape quite nicely, no spraying. It's great at making a very thin line that I can't get with a pencil.

I use this on my brows which are very light and pretty shapeless... I use this brush with Benefit Brow-Zings in 04 (I dye my hair black, that's why) and WOW. Perfect arches that get SO MANY COMPLIMENTS on a daily basis. I used to use the little brushes that came with the browzings, but since I moved on to the MAC 266... wow. My brows look totally natural, perfectly arched, completely flawless.
Works pretty well as a liner brush, too!

It's the best. period. It was recommended to me by the MAC representative at my local mall and she couldn't of hit the spot better! Perfect for lining eyes, dry or wet. definitely stupid/shaky hand-proof! It's very versatile for smokey to defined looks, it's my #1 liner brush pick.

I lost this brush & re-purchased it, the bristles & the angle of the brush are awesome for the eyes! continued >>

I didn't realize that I owned this "famous" 266 brush, but I decided to look at the brush I used every day to line my eyes and it's a 266 MAC. Don't recall buying this one, but it's the ONLY brush I use to line my eyes. The angle and thin bristles are perfect for using shadow or pigment wet, which is what I prefer to line with. Absolutely indispensible in my brush collection.
