Skin Monarch Flat cartridges have needles soldered in a single straight row. Depending on the angle of the pen, a Flat can create crisp, sharp lines or broad, even strokes, which makes it a versatile configuration for structured PMU work and geometric tattoo details.
The collection features Prince Touch 250 Flat Cartridges, a precision flat-needle cartridge from the Prince Touch 250 system. For an angled version of the flat row, see our Slope cartridges, which let you switch between lines and shading by adjusting the pen angle.
Compare Flats with Round Liner cartridges for fine hair strokes and Magnum cartridges for wider coverage, or browse every configuration in cartridges. To try several needle types before ordering a full box, see our cartridge sample sets.
Use Flat cartridges with a compatible PMU machine and Skin Monarch eyebrow pigments, and practise new hand angles on practice skin before working on clients.
