Review (5/5): Highly satisfied!
My only regret is not going with the XL but thats only because I have a ton of makeup. If you only have a few brushes and some powder and mascara or the basics, a small or medium would be fine. The large holds 2 full sets of brushes, and maybe 40 other items. This is the best and most organized case I've owned. Best of all, it keeps your makeup in place so even if it does get tossed around, everything is secure.
