Description
The K6003 stands out from Biomaser's other wireless pens for one specific reason: flexibility in how you power it. It ships with two battery heads and an RCA head, so it can run fully wireless or plug into a standard power supply when you'd rather not manage batteries during a long shift.
Its 12V coreless Swiss motor runs up to 10,000 RPM through a 1000mAh battery, giving roughly 2-4 hours per charge in wireless mode. Where it earns its keep is in its four distinct working modes: a regular continuous mode, an intermittent stop-start mode useful for beginners learning technique, a gradual mode for dark-to-light color transitions, and a hitting mode built specifically for hairstroke and misty eyebrow work with adjustable speed and force.
At 117.2g and 23 x 139mm, it's on the heavier side of Biomaser's pen lineup, though still built for one-handed procedural work. Takes universal cartridge needles.
