Flat Open Magnum (FOM) Tattoo Cartridges | Maverick Supply Co.
Visibility and Volume: A Guide to Flat Open Magnum (FOM) Cartridges
At the end of the day, we do what we do because we love the culture and the craft. There is a specific kind of satisfaction in laying down a block of solid black or saturated color that doesn't need a second pass. Part of reaching that level of efficiency is being willing to stay curious—experimenting with different magnums is how you find the "brush" that matches your specific hand speed and vision.
While closed magnums offer stability, the Flat Open Magnum (FOM) is built for the artist who wants to see everything. If you’ve been looking for a tool that offers maximum visibility for heavy saturation and geometric precision, the FOM belongs in your setup.
What Exactly is an FOM?
The Flat Open Magnum (FOM) 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, making it the powerhouse of the "hard fill."
The "Open" part of the name refers to the plastic housing tip. In an FOM, the top of the needle grouping is exposed. This design offers two distinct advantages:
-
Unmatched Visibility: You can see exactly where your needles are hitting the skin. This is a game-changer when you are cutting into sharp corners or working up against a precise outline.
-
High-Volume Ink Flow: The open-tip design allows for a more generous ink dump. It keeps the needles saturated longer, ensuring you get that "wall-to-wall" color without having to fight for flow.
Why You Should Experiment with FOM Configurations
We always encourage artists to step outside their go-to groupings. If you feel like your current magnums aren't dumping enough ink or you’re tired of "guessing" where your needles are landing, the FOM might be your new favorite tool.
The King of Large-Scale Saturation
For those massive projects—heavy blackwork, large traditional pieces, or geometric sleeves—we offer a range that goes all the way up to a 49FOM. When you have that much surface area to cover, the FOM ensures you are moving efficiently and packing solid.
Clean, Hard Edges
The straight-across grouping of the FOM is designed for precision. It allows you to "block in" color with a level of edge-control that curved mags can't match.
The Maverick Standard: Every FOM we ship features our long taper, precision-polished needles. We don't cut corners on the finish because we know that a smoother needle means a better experience for the client and a cleaner heal.
