For permanent makeup (PMU), control and consistency are everything. Whether you’re defining brows, enhancing lips, or crafting the perfect eyeliner wing, your tools need to work as hard as your technique.
That’s why professional PMU artists turn to the powerhouse combination of Grip Needles’ 1RL and 1RL/3 Triad hybrid cartridges: a duo designed to balance micro-level precision with time-saving efficiency.
Why 1RL Is a PMU Essential
The 1 Round Liner (1RL) cartridge is a staple for detail-heavy PMU work. With its ultra-fine tip and tight configuration, it allows for pinpoint pigment placement with minimal skin trauma, especially important when working with sensitive or textured skin.
Best For:
-
Lash line enhancements
-
Hair-stroke brows
-
Lip contouring and line work
Why Artists Love It:
-
Ultra-fine diameter for clean, controlled work
-
Excellent for tight curves and delicate structures
-
Deposits pigment smoothly with easy healing outcomes
What Makes the 1RL/3 Triad a Game-Changer
The 1RL/3 Triad is a proprietary hybrid configuration combining three 1RL needles in a triangular formation. This setup increases pigment saturation while maintaining the control artists need for soft blends and shading.
Best For:
-
Powder brows and pixel shading
-
Lash line fills
-
Soft ombré blends for lips and brows
Benefits of the Triad:
Even pigment dispersion with fewer passes
-
Reduced skin trauma over time
-
Faster coverage without compromising detail or shape
