The best brush I have for eyelining Review: It's Nice brush! - Works great for highlighting under and around eyebrows. Medium firmness - perfect firmness for the application that I use it for. Brush is a good quality, no shedding bristles, and doesn't seem cheaply made. Not sure if it is authentic Sigma since this is one of my first buys,but I LoVE the brush regardless. For those who would like to know it reads: Paten Pending on one side of the ferrule and then on the other side the ferrule reads: Sigma and the style number is engraved at bottom ferrule under the last crimp. I posted a pic. Overall it a great brush and a must have for me! Update 1/31/2016: This brush has been going strong and has become a staple tool for shaping my brows and higlighting my brow bone. Still no shedding and a True Keeper! ## Features - FOR SHARP, WELL-DEFINED LOOKS: Achieve captivating eye looks using the flat, slender edge of this E15 Flat Definer Brush.

I'm looking for a brush to do a fairly fine line.** A: The brush is flat and a little too wide for what I wanted, but it's still a great brush. I do use it for filling in and brushing the brow. Sigma makes a small, flat, angled brush for lining your lids but I use for my eyebrows. I have very sparse brows and need a small brush to set a line. **Q: Is this synthetic?** A: No it is not. It is an amazing brush. I use eyeshadow a lot for eye liner and I use this brush exclusively for that. Sigma brushes are amazing . Hope that helps. **Q: Is the e15 good for doing eyebrows?** A: I never used it for that purpose, wouldn't an angle brush be better for that purpose? I use it to smudge colour on my bottom lid **Q: Is this brush good for the waterline?** A: Don't use it for my waterline. I use this brush with concealer to clean up my eyebrows after drawing it in. I'm sure you could use it for bottom waterline ## Customer Reviews ### ⭐⭐⭐⭐⭐ Top quality! *by A***V on January 15, 2026* Very high quality brush!!
