The Thorn is a full-length wireless pen built for artists doing bold lining, color packing, and traditional work day in and day out. Its fixed 4.0mm stroke delivers consistent, solid hits, powered by a Swiss DC motor rated at 11,000 RPM for smooth, stable output. A single 1800mAh battery covers a full working session, with four memory voltage presets so you can switch settings quickly between clients without resetting from scratch. The 9V jump start handles cartridges that need a little extra kick to get going. Built with overload and short-circuit protection, the Thorn is made to hold up to daily studio use.
