Description

FK IRONS TIDAL: THE FIRST ARTIST-SELECTED COLOR OF THE YEAR

A limited-run colorway chosen by artists. FK Irons asked its ProTeam artists to vote on their favorite new finish, and Tidal—a striking aquatic teal—came out on top.

As FK Irons’ first-ever Artist-Selected Color of the Year, Tidal is available as a limited-run special edition color across four of the brand’s most trusted wireless tattoo machines, including this one.

Reimagine daily versatility with a machine that handles everything. Building on the fan-favorite features of the OG machine, the FK One Update is designed as a true all-rounder for artists who don’t want to switch machines mid-flow.  

Power through longer sessions with upgraded batteries. Dual rechargeable batteries (18500A & 18650A) give you flexibility and endurance, with up to 5.5–6.5 hours per battery depending on configuration. Plus, the battery housing comes with a refined 1.1” digital LCD display so you can clearly see your voltage and all your settings at a glance.  

Say goodbye to fatigue with unmatched ergonomics + efficiency. Weighing in at just 215g (233g with battery), the FK One Update is built for control without heaviness. It integrates seamlessly with Ergo Shield grips, cutting setup time down to seconds while improving comfort during long sessions. 

Choose the stroke that’s right for you. The FK One Update comes with a 3.0mm or 4.0mm stroke according to your preference. With a 5V–12V (80Hz–180Hz) operating range and precise incremental adjustments, artists can fine-tune machine performance to match their technique, workflow, and client skin response in real time.

"Great machine great price"

— Jose S. (5/5)

Good

"Good machine and powerful. It will get the job done. What they don’t tell you about this machine is about the motor in it. The motor is a brushed motor, which I was disappointed to find out. As for the life span of the machine is decreased. For this price I would buy the Exo for 30.00 more. Which has a brushless direct drive motor."
