– E15 Flat Definer – Flat-Angled Professional Makeup Brush for Sharp, Defined Application – Eyeliner Tool for Liquid, Gel & Powder Eye Makeup

I did not expect it to be that good. This was my first ever purchase from Sigma and I bought flat brush because I needed this special shape for tightlining: - bristles, size and handle placement - it all looks and feels so high quality. In the real life way better than on the pictures - the weight and length is so comfortable to use - it touches my lash line and stays without sliding and easily transfers waterproof pencil or shadow - easy to apply

Sehr schöner Pinsel sehr gute Qualität kann ich nur empfehlen.

This brush is fantastic for lining, shadows, and brows. It has a surprising number of functions. While I find Sigma brushes to be a little scratchy in general, the overall use of this brush was completely worth it. It’s wider than I expected, but that actually just made it fill a hole that wasn’t already taken in my collection.

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!

Great quality. Retains its shape after usage.
