Under Eye and Nose Brushes
I make sure I have a fresh set of brushes for under my eyes and to contour my nose. The blending under my eyes and with my nose is very delecate and I can't have any old residue on the brushes and risk color contamination. If you accidentally swipe from eye shadow under your eye, you can't cover it up. You have to wipe it all off and start over and it never matches when you work like this.
These brush sets come in at less than $2 a set of 5. 10 sets per box.
