Upgraded brush: This double-action brush does not require a switch, just press the trigger and work quickly, release the trigger and automatically stop working, making it easier to use. Higher pressure delivers a thicker coating faster and over a wider area. Ideal for painting models, crafts, cake decorations, car graphics, temporary tattoos, fine art, manicure, etc. BETTER CONTROL: It is a special "double-action airbrush" that is different from traditional double-action airbrushes. You can turn on and adjust different air pressures by pressing the on/off button. You can then adjust the amount of paint by sliding the trigger back. Internal mixing provides the most consistent, smooth results because the paint atomizes better with this method. This gives your paint a more even distribution, allowing for better control. Longer working time and low battery reminder: The spray gun is equipped with a Type-C charging cable. Due to the upgraded circuit and battery, the time after full charging reaches 1-2 hours during operation, while others can only reach 30-50 minutes. It is not recommended to use the airbrush kit while charging. When the battery is low, the air compressor will continue to vibrate slightly to remind you to turn off and charge.
