1 oz bottles are half the size of the ProAiir 2 oz bottles. With a 20mm top, they fit with regular caps, snorkle caps, or easy twist caps! 

Attach a snorkle cap to this bottle to add to your siphon-fed airbrushes! With a smaller bottle, you can fit your airbrush into tighter spaces, and it provides less stress on your hand a wrist. 

Perfect bottle for mixing your own custom ProAiir colours in!
