Anon who talked about screwed up screws and asked for airbrush shilling recently here. I think my mistake was to go through the screw with the cleaning brushes like pic related, in the long run it very likely damages the screw. I ordered new screws, and decided to get a H&S evolution 2024 with 0.28 and 0.45 nozzles as new airbrush. It comes with two cups, 2mL and 5mL. Kinda bothered since I'm used to 10mL but if I use it just for details it won't be a problem
