About Sonia G. Flat Definer
The Flat Definer is a mini shader, smudger, and precision flat pencil brush. It's flat and thin but has enough density to remain stable and achieve a neat and even application. It's firm with sufficient flexibility and softness at the tip to not pull or skip on the skin.
Its main purpose is to provide definitions along the bottom and upper lashline, but it also works nicely as a precision shader for the inner mobile lid, the outer v, to place a sparkly accent or act as a little smudger brush.
"I was looking for a brush small enough, yet strong enough, that did not poke or pull the sensitive skin around our eyes." — Sonia G.

Perfect for Shadow Liner!
I've tried to use the smudger two and smudger one for shadow liner, but it doesn't work optimally for the upper lashline because it doesn't glide very far, so you have to redip into the shadow a couple of times. They are great brushes for the lower lashline though!
Enter the flat definer! It glides so smoothly across the upper lashline. It is perfect for shadow liner. I have to put on mascara before doing eyeshadow because a lot of mascara transfers to my lids since my lashes are so short and thin. Point is, the flat definer can get extremely close to my lashline even though my lashes are curled and in the way. It's so useful especially when it comes to lining the inner third of the lashline. If it wasn't obvious enough already with all Sonia G brushes, this brush is incredibly soft and doesn't skip on the skin.
All in all, it is the perfect upper shadow liner brush that can also be used to precisely place shadow when used on it's flat side. Highly recommend considering!10 found this helpful.Aubrie V. Apr 19, 2020
Perfect, but not for what you think.
This is my all time favorite brush for concealer. It is truly what I have been looking for all my life. Small, but not too small, firm, but flexible, and oh so soft without being flimsy. Perfect! I bought two, and may need to buy more as backups. Thank you Sonia G!6 found this helpful.
