These nozzles are very easily damaged in some unforeseen way, and I find having the spare parts on hand very good at keeping my mind at ease. I recommend to everyone to keep spare parts for their airbrush on hand because you never know. The service that I receive from maple airbrush is second to none.
It's really great to be able to buy parts for your Iwata and Badger brushes in Canada. Hopefully Maple Airbrush will soon stock Harder and Steenbeck parts
