EP9 — Angle‑Adjustable Voltage Rotary Tattoo Pen

The EP9 is a rotary tattoo pen that replaces buttons with angle‑based voltage control — simply rotate the grip to adjust power. Choose between Shader (3.5mm) or Liner (4.2mm) stroke configurations. Powered by a replaceable 18500 battery, the EP9 keeps things simple: no screens, no menus, just intuitive analog control. Needle protrusion ranges from 1.5mm to 5.0mm. Note: Correct battery orientation is required before use.
