Ultron 4

The Ultron 4 isn’t just another pen; it is the culmination of years of engineering designed to replace your entire arsenal. Whether you are pulling crisp single-pass lines, blending smooth realistic shadows, or packing saturated color, the Ultron 4 adapts to your style—not the other way around.

Why choose the Ultron 4 series?

At the heart of the Ultron 4 is the revolutionary SmartHit technology. Unlike traditional rotary machines that hit with a constant force, the Ultron 4 detects skin resistance and adjusts the motor response in real-time.

• Less skin trauma: Faster healing times for your clients.
• Maximum control: Choose from 7 distinct hit modes, from ultra-soft for delicate shading to rock-solid for heavy lining.
• All-day comfort: A low center of gravity and ergonomic grip designed to eliminate wrist strain during long sessions.

Engineering meets versatility

The Ultron 4 series is built around the high-performance M3Pro brushless motor, ensuring consistent torque even at low voltages. Whether you prefer the specialized feel of the 3.7mm, 4.2mm, or 4.7mm fixed strokes, or the total freedom of the Ultron 4 Pro with its adjustable 3.2–5.5mm stroke, you are holding the most versatile tool in the industry.

"With the Ultron 4, we didn't just build a wireless pen; we built a machine that understands the skin."
