Traditional coloring tools, such as brushes, tend to leave brush marks during application, resulting in uneven coloring. The airbrush, however, uses compressed air to atomize the pigment and spray it evenly on the surface of the hand puppet, avoiding pigment buildup and uneven thickness. Whether it is a large area of the base color spread, or a small area of the details of the coloring, the spray gun can ensure that the color is uniform and consistent, so that the color transition of the hand puppet is natural and smooth, presenting a flat effect like professional-grade printing.

Nendoroid figures often have intricate details, such as character facial expressions and clothing textures. The adjustable nozzle of the airbrush allows for precise control of the amount and range of the paint to be sprayed, allowing for the drawing of extremely fine lines and the coloring of tiny areas. This allows the colorist to easily handle those delicate details on the figures, such as the pupils of the eyes, hair, etc., to perfectly present the beauty of the details of the figures and make every detail come to life.

For larger sized figures or models that need to be colored over a large area, coloring with brushes can take a lot of time and effort. The airbrush can quickly cover the surface of the figure by spraying a large area, greatly reducing the coloring time. Even for small figures, the airbrush can save coloring time and improve production efficiency by virtue of its efficient spraying method in the process of repeated coloring, making the coloring work easier and more efficient.

The spray gun can easily mix different colors of pigments and create countless unique colors by adjusting the ratio. Moreover, when making color gradient effect, the spray gun can achieve natural color transition by controlling the spraying distance and the flow of the pigment, from light to dark, from warm to cold, easily creating a variety of gorgeous color effects, meeting the colorist's demand for color diversity and adding unique artistic charm to the hand puppet.

When brushes are used for coloring, due to direct contact with the surface of the model, it may cause scratches or damage to the model due to improper force. The airbrush, on the other hand, sprays the paint onto the model through airflow without direct contact, effectively reducing physical damage to the model and allowing the model to be better protected throughout the coloring process, ensuring the integrity of the model.
