Anticipation said, I am not a professional. The bag I wanted to hobby purposes and for storage of my brush. So I have no idea whether they or similar for proper work as a make-up artist, make-up artist is suitable. I still hope that I can help you with your decision.
From the outside the bag looks very high. It is larger than I expected, so no one looks out my brushes or combs. It is clean and sewed the material not to feel all factitiously. Yes, the smell is a bit strange, but I'm not as sensitive and if you let air out the bag and purified before use, then this is soon gone.
The subjects are a good size. Although they are in principle all the same width, but it can be (so far) stow both thick and thin brush well, no, that they slip or even fall out. In the larger front pockets even fits my makeup blender.
The problem with the belt, which can not be set right, I've also found. Originally my plan was, however, proceed with a safety pin or to sew a Velcro closure, but my friend had solved the problem within a few seconds even easier: Just take the tape and again from below through the loop. Thus, it holds very well so far.
Conclusion: I forgive 5 stars because the bag has not shown me any defects and has especially great value for money.
