Review (5/5): Highly recommended
I used to use a regular white towel, then a microfiber towel, then tried a hair bun insert but this product has proven itself better than any of those others. It works on synthetic and natural brushes and all powder products, blush, bronzer and eyeshadow, that I have tried it with. I know many people think it is an overpriced gimmick but I use mine daily and am very happy with it. I still shampoo my brushes about every week to ten days but because I can now reuse brushes from day to day I don't have nearly as many to wash. It doesn't look bad sitting on my vanity and the top of the tin makes it easy to travel with. I think it is better for my brushes (and skin) than the quick drying solvents that can be used to clean brushes quickly. I definitely recommend it.
