The Copic Airbrush System, while an innovative tool for artists, does have a downside regarding ink usage. Given its nature, the airbrush mechanism disperses ink in a fine mist, which inherently leads to some degree of ink dispersal beyond the immediate target area. Consequently, compared to direct application methods like drawing or coloring, using the airbrush feature can deplete your Copic markers' ink supply more rapidly. It's important for artists to weigh the unique effects achievable with the airbrush against the potential for higher ink consumption. To mitigate waste, plan your projects carefully and consider the airbrush as a tool for specific effects rather than for extensive coverage.

While titanium dioxide is generally safe in everyday settings. there are worries about potential health risks associated with its nanoparticles if consumed or inhaled excessively. Particulate exposure for brief periods is typically benign. but prolonged or extensive contact should be avoided. Hence. it is crucial to handle products containing titanium dioxide nanoparticles with care. Health authorities are currently examining the use of titanium dioxide in consumer goods such as food and cosmetics.
