The inside flap isn’t attached to the bottom in the middle, but it is 100% not a problem. It fits all my makeup brushes, nail files and even a brush cleaner. I was very satisfied because i like the quality and honestly expected a fake feel to it but no. It holds everything in nice but also a disclaimer — you might not think it will close or take shape correctly because when it arrives it is flat, i just put some makeup brushes and once you zip it up. It works! But i will be buying again if it ever gets ruined because for the price i’m honestly impressed
