The Olympos Summit-523 Airbrush Brand New. I have several Summit, selling one of them. The head design of 523 is identical to richpen 223 which also means the nozzle size is smaller than 0.3 can produce hair lines. It performance just like any micron airbrush, absolutely top level. The side feed cup parts is self made design for Iwata cups, I personally find Iwata cups easier and more universal. It works perfectly with the adaptor and I included two of them. Unfortunately I don't have the original case come with it, if you have one it will looks like the reference photo I showed, very good for collection as well.
