The brush roll up was a game change for keeping makeup brushes organized for travels and everyday use, and also keeping cleaner from not rolling around in the bottom of other bags!
I love the Brush Roll for the multiple uses! I have one for lip gloss/lipstick and mascara's, one for brushes and one for pens, pencils, markers, etc. The only makeup brush that will not go in a pocket is a double-sided brush. But that is not a problem, I just lay the double-sided brush in before I roll it up and I have never lost it!
