Airbrush MakeUp Kit

I got this kit in esthetician school in March (2024). I used it twice to “learn” how to use it but have no interest in doing airbrush makeup. Some of the makeup is opened but some came with no plastic on the tubes either. Barely used this unit and cleaned it thoroughly. Absolutely nothing wrong with it at all, I just have no desire to use it now that I’m done with school. School charged me $900, which is what it also is on the MUD makeup site.
