The UNi-B Wireless Tattoo Machine is built for artists who want maximum flexibility from a single machine. Featuring a continuously adjustable 2.5mm–4.5mm stroke, the UNi-B lets you fine-tune your stroke without being limited to fixed presets. Whether you're working on soft shading, smooth color packing, or bold lining, you can dial in the setting that best matches your technique.
Powered by a 10,500 RPM AVA metal brush DC motor, the UNi-B delivers responsive, consistent performance while allowing effective operation at lower voltages. Its replaceable 18500 battery provides approximately 6–8 hours of working time, while an upgraded protection circuit helps protect the machine even if the battery is installed incorrectly.
A clear color HD display keeps important information visible at a glance, including voltage, frequency, session time, and remaining battery power. The built-in rebound system is designed to respond to skin resistance, helping create a smoother tattooing experience while reducing unnecessary skin trauma.
