Finally, Sigma has the brush cup holder for sale! In the past, you had to purchase one of the "Make Me Up*" kits in order to get the brush cup holder too. I was not going to pay $99 just for the brush cup holder. Sigma is now selling it individually for $20.
The Sigma Brush Cup Holder is great for travel and for storage. When you open it, it turns into 2 brush holders. You can put all your face brushes in 1 cup and your eye brushes in the other cup to be more organized. Also, the cup holder isn't just for Sigma brushes. Brushes from other brands will fit inside it too.
You can get the Sigma Brush Cup Holder here* for $20. Also, you can get 10% off all orders. Just enter code GLOW2011 at checkout. Coupon expires July 31.
