The Mercury turns your skill into mastery.
You’ll feel like everything you’ve tried before finally comes together, unlocking your full potential—the potential you always knew was there
When it comes to Mercury, our goal was simple: create a machine that gets better in every way — hit, size, ergonomics, battery, efficiency… But that wasn’t always the plan. We originally set out to make something more radical and disruptive, but halfway through development, I had a change of heart after reading a chapter in an amazing book: Diary of a CEO. The chapter was called ‘You Must Sweat the Small Stuff,’ and Steven Bartlett talks about the idea of improving by just 1% at a time. It’s more effective to focus on small, sustainable improvements that add up to create solid value.
Thanks to this approach, we’ve managed to boost the motor’s efficiency by 14%, balance the machine’s weight by 8%, increase needle feedback by 18%, and extend battery life by 50% (wow!).
This isn’t a radically different machine; it’s just a better machine. And we truly believe it’s going to be your favorite because you won’t have to adapt to it—Mercury will adapt to you.
Power port compatible with magnetic batteries by Critical/Bishop
Designed to work with our ROVER R-1 Universal Battery (10h to 15h)
Available RCA cap adapter to convert the Pen to cord-operated
Fixed strokes:
4.3 – 3.5 – 3.0 (mm)
Direct drive system with enhanced feedback and precision
Faulhaber Motor 4.5W
(Brushed, rapid response)
Tip weighted design with downward balanced force
Comfortable for the pendulum-like motion typical in shading or whipshading techniques
This is where things get interesting.
The Mercury M-1 is an incredibly efficient machine. Expect 10 to 15 hours of battery life with our ROVER R-1 Universal.
Right now, you’re probably thinking:
“Great, that means I can work an entire day without worrying.”
And that’s exactly what we aimed for—a battery life long enough to give you peace of mind. No more finishing your session with a flashing low-battery warning that makes you nervous.
Plus, the ROVER R-1 uses replaceable lithium cells, so say goodbye to the problem of throwing away a battery after one year of heavy use, as happens with sealed units. With the ROVER you can buy new cells at any electronic store and keep using it for years.
The lithium cell inside the ROVER R-1 is a standard 18350 flat, with a 1,400mAh capacity and a 3A max current.
And if you already own a Critical/Bishop battery that’s compatible with this power port, you can use it too (in fact, you should!).
Battery life will depend on the capacity of the battery you’re using, so your runtime will vary accordingly.
The weight of the machine is concentrated at the lower end.
The design is ergonomically optimized for shading, whipshading, and detailed linework, providing the artist with ultimate comfort and control.
The 36mm grip features a smooth, tapered design that ensures a firm hold—even at the very bottom, ideal for fine detail work.
At the core of Mercury is a 4.5W German Faulhaber motor—the same high-end motor found in other top-tier machines. It has an impeccable reputation, but we’ve taken it to the next level with a custom-designed heatsink.
This heatsink helps keep the motor cool, so you can push it harder for longer without overheating. And that matters—because when motors get too hot, they lose power and slow down.
To get the best heat dissipation, the heatsink is firmly attached to the aluminum chassis with thermal paste, making it even more efficient.
The motor has been meticulously tuned to match the unique feel and response of its stroke length—3.0, 3.5, or 4.3 mm—ensuring that the machine moves exactly as you expect it to.
Each of these three motor configurations has been refined to bring out the best in your technique, making the machine feel like a natural extension of your hand.
The innovation behind the heatsink brings up to a 114% improvement in performance!
The heatsink keeps the motor at its optimal working temperature, no matter what
