The Iwata HP-SB airbrush has a 0.2 mm tip size and 1/8 oz. (3.5 ml) side-feed color cup. Side-feed cup allows for right or left-handed use, and for slower detail spraying and better vision of the work surface. Optional 1/4 oz. side-cup, 1/2 oz. gravity cup or a 1 oz. siphon bottle add to the versatility of this airbrush.
