FK Irons One Update Tattoo Machine 4.0mm Stroke - Tidal

Tidal is FK Irons' Limited Edition Artist Colour of the Year, here on a machine built to stay in your hand from your first line to your last. The One Update runs a fixed 4.0 mm stroke that handles lining, shading and packing colour in a single setup, making it one for the tattoo side of your work.

Dual battery compatibility makes such a difference across a full day: 5.5 to 6.5 hours per battery, a spare already in the box, and quick recharging in between. The 1.1" LCD keeps your voltage and settings clearly in view, adjustable in gentle 0.2 V steps across a 5 to 12 V range, so fine-tuning never feels like guesswork. At 215 g it's balanced for control and comfort, and it works directly with Ergo Shield grips for a quicker, more natural setup.
