## Questions & Answers

**Q: How flat is this 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

### ⭐⭐⭐⭐⭐ Fantastic, multi-purpose eye/brow brush!
*by B***N on August 10, 2025*

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.

### ⭐⭐⭐⭐⭐ It's Nice brush!
*by S***N on October 21, 2015*

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!

### ⭐⭐⭐⭐⭐ I compared my cheaper one with this & here's the difference
*by S***R on September 6, 2019*

I have another flat definer brush from beauty junkees. The quality of their brushes for the price is good & their flat definer is a good brush. I've been very curious about Stila & if it's worth the price. The two brushes are the exact same size. Only visible difference is bristle color. Both have same sturdiness. But, here's the one difference that made the Stila better. When you run your finger across the top of the Stila brush? Feels like velvet. When you do the same with a "cheaper" version, it's not as smooth. To the touch, the difference is small. However, when you are running the brush across your eyelid, you can apply your liner smoothly. I tried the cheaper brush on one lid & the more expensive on the other. It takes a few more brush strokes with the cheaper version to achieve the results of this brush. If you're on a tight budget, stick with the cheaper one, it still does the job. I'm glad I tried this out, think I'll buy another one of these, but not ready to invest in a large expensive set.
