Nice brush
I really like this brush to fill in a large area of colour when doing nail art. It's also super handy for full cover colour on nails too. The way the bristles are position gives a really clean finish

Straight to the point!
I was quite honestly shocked at how much I liked this straight cut application brush. I can use it with such presicion even on the most rounded nail/folds. Had to attach a little vid of this one in action. It's a gem for colour or builder applications
