Built to Adapt, Engineered to Perform 

Enjoy versatility with no limitations when you tattoo with the FK One Adjust. The FK One Adjust is built to adapt to any style, so you can pursue any project for any client. This patent-pending stroke adjustment technology delivers effortless adaptability, so you can tackle any technique on the fly. Easily adjust your stroke mid-session without ever having to power off your machine. One setup handles everything: no need for swapping machines or cams mid-session. 

Enjoy nonstop, all-day wireless performance with 2 swap-and-go rechargeable batteries. Each FK One Adjust comes with one large battery for up to 6.5 hours of power, and one small battery for up to 5.5 hours (depending on your settings and operating parameters). This machine also gives you a dual-slot charger, so you can always have a battery powering up and ready to go when you need it. 

Get full visibility and control over your performance. The FK One Adjust features an upgraded digital display that gives you a crisp readout of your operating voltage or hertz according to your preference. Why Hertz? Hertz offer a more accurate measurement of your machine’s performance, showing the exact frequency of needle movements per second.  

Trust in the FK standard, knowing the FK One Adjust has an artist-first design. This machine was built with artist input and is specifically designed to handle everything you throw at it day after day, session after session, from first line to final pass. It’s reliable, durable, and built to last, supported by FK’s global service program. 

HOW THE STROKE ADJUSTMENT WORKS

The FK One Adjust features an innovative custom engine that redefines adaptability. A fixed-stroke cam connects to a precision paddle, while a rotating slider adjusts stroke length by moving closer to or farther from the paddle’s center. This design reduces friction and wear, keeping performance consistent session after session.

A first-of-its-kind system built to keep your flow uninterrupted and your performance unmatched.

Esthetically sound, materially flimsy
Color: Beige, Size: 4 Panel-67”
The item at first seemed okay and quality was good. But it’s a little flimsy and tips over frequently. I’m thinking of returning and replacing pretty soon.

Perfect for working from home, creating privacy in my home office.
Color: Beige, Size: 4 Panel-67”
Easy to put together, took about 10 minutes by myself. I laid it on the ground folded (make sure the same direction for the brackets match). The only issue I had was one screw would simply not go into one side of the connectors. Using it as a background for my home office, so it won’t be moved often, so not super concerned, not enough to take the rest of it apart to see if I could fix the issue. Looks great, creates the privacy I needed for meetings.
