I remember the first ever blending brush I bought, it was a Ruby and Millie dealy which I bought with my Boots voucher.
It was pretty good for a noob like me so I decided to buy more of their brushes..
Then I came across their liner brush which (I thought) would be heaven for those who had abandoned any hope of ever being able to use liquid liner properly.
This brush was the biggest disappointment ever and this is why:
It didn't work from the off.
I thought it might be a dodgy one but I know a few people who have this and they have said the same. I used it with a Stila smudgepot, a Bobbi Brown gel liner and various powder liners, in all instances all I got was a scraggly line. Nothing like the smooth application that it boasted. I thought washing it might help but it didn't do anything. I've still got it in my brush collection but it's languishing at the back.
However, their i-Liner brush is very good. I used it to do this look and it works brilliantly when you're using a dark shadow as a liner on either your eyelid or to set the pencil on your waterline. The only issue I have with that brush is that it's a bit long..you need to hold it at an angle but it picks up a nice amount of colour and for 50p, you can't ask for more.
