I wanted to convert my Iwata Airbrush from it's current needle size of .35mm to .5mm. I emailed to find out what I needed and was promptly responded back with the correct part's list required. Also spoke with Donna, who was a great help in explaining what was required and also provided a few tips on some airbrush techniques. I've ordered before and have never been disappointed.
This is a 'spare' so I haven't opened it yet, but it's the correct part and it arrived quickly and safely. Thanks!
