ProAiir Ink is alcohol-based temporary tattoo ink that is waterproof and durable for 5-10 days. Pro Aiir ink is certified as “skin safe”. You can airbrush the ink at 18-20 PSI without clogging or fogging. Because of the need of rubbing alcohol or baby oil to wash it off, ProAiir Ink is recommended only for tattoos. For face and bodypaint we recommande to use ProAiir Hybrid.
