Review (4/5): handy for finding the exact brush you want
This seems quite a durable folder to store makeup brushes in. It's clear and makes it easier to see and grab the brush that you want right away rather than having to dig for it in a makeup bag.
For the makeup brushes that I am trying out with this bag, there is a little 'collision' between the bigger brushes, but I think their handles may be rounder than other makeup brushes. At first I was worried because the tops of the brushes were sticking out the top of the flap and then I looked at the pictures on the product page again and realized that I had the brushes in upside down. So I took them out and put them back in correctly and only a little bit of the bottoms of the brushes stick out, and one head of a brush that is double sided.
I know this says that it is waterproof and I'm sure it is, but the sides of this folder like case don't have snaps or any sort of closure, so water could potentially get in the sides. But generally I don't think one would have the case out in the open where it could get wet anyway.
