Review (5/5): There is a reason for duplicate brushes.
Duplicate size brushes are included because we ALL use multiple colors. This way you're getting true color, not a blend of 2 different colors, i.e., blue/yellow = green etc. You don't want that. Especially when you're applying a specific cream color but you used the brush already for a smoky gray...right? Same with lipsticks. No more complaints about duplicates ladies. Be grateful they have them in this amazing kit.
