Power and Precision: A Guide to Flat Closed Magnum (FCM) Cartridges
At the end of the day, we do what we do because we love the craft. There is a specific kind of pride in seeing a block of color that is packed so solid it looks like it was printed on the skin. Part of finding that perfect finish is being willing to stay curious—experimenting with different magnums is how you evolve and find the "brush" that matches your hand speed.
While curved magnums are the kings of soft blends, the Flat Closed Magnum (FCM) is the king of the "hard fill." If you’ve been looking for a tool that offers maximum stability for color packing and geometric work, the FCM belongs in your setup.
What Exactly is an FCM?
The Flat Closed Magnum (FCM) features our high-quality #12 (0.35mm) needles arranged in a straight, horizontal line. Unlike a curved mag, every needle in a flat mag makes contact at the same depth simultaneously.
The "Closed" part of the name refers to the plastic housing. In an FCM, the needles are fully encased by the cartridge tip. This design provides two main benefits:
-
Maximum Stability: The closed tip acts as a rigid guide, virtually eliminating needle "chatter" or vibration. This allows for incredibly clean edges when you are working up against a line.
-
"No-Spray" Ink Control: The closed tip holds the ink closer to the needles, preventing the "ink spray" that can sometimes happen with open mags. This keeps your station cleaner and your saturation more consistent.
Why You Should Experiment with FCM Configurations
We always encourage artists to step outside their usual go-to groupings. If you’ve only ever used curved magnums for packing color, trying a flat mag might be a "lightbulb" moment for your style.
Perfect for Geometric & Tribal
If your work involves sharp corners and heavy black-fills, the FCM allows you to "cut" into edges with a level of precision that a curved mag can't quite match.
Saturated Color Packing
The straight-across grouping of the FCM is designed to deliver a high volume of pigment into the skin evenly. It’s a powerhouse for traditional styles and any work requiring wall-to-wall saturation.
The Maverick Standard: Every FCM we ship features our long taper, precision-polished needles. We ensure the finish is flawless so you can achieve that "solid-as-a-rock" saturation with minimal trauma to the skin.
