RL Round Liner BMX Screw SMP Permanent Makeup Cartridge Needles for BMX Permanent makeup Machine 10PCS

BMX EYEBOLT Needle Cartridges only fit for BMX machine

Description
The 2RL - 0.30mm dual-needle grouping is the SMP artist's balanced workhorse — fuller than a 1RL, tighter than a 3RL — ideal for scalp follicle impressions, lip contours, and defined eyeliner. This backflow (bf) version integrates a back-flow prevention membrane inside the cartridge: pigment, blood, and fluids cannot travel back into the machine body, protecting both your client and your device.
Choose the backflow version when you work with liquid pigments, run long SMP density sessions, or operate under strict hygiene protocols.

Key Features
Dual-needle 2RL round liner — balanced saturation for SMP and PMU contour work
Integrated back-flow prevention membrane — pigment never enters the machine
0.30mm (#10) diameter — versatile standard gauge
316 medical-grade stainless steel needles, 100% E.O gas sterilized

Material: backflow

Best For
Liquid-pigment SMP sessions, high-density scalp work, lip contour with fluid pigments, studios with strict cross-contamination protocols

Description
When the brief is inv isible realism, reach for the 3RL 0.18mm. Three ultra-fine (04-series) needles in a tight round grouping produce nano-scale hair strokes, whisper-fine eyeliner, and micro-detail work that 0.25mm needles simply cannot match. This is the cartridge for
nano brows, fine hair-stroke layering, delicate lash enhancement, and tiny SMP touch-ups.
The metal-tip (mt) version delivers maximum rigidity at this ultra-fine gauge — critical, because thinner needles flex more. The stainless tip holds the 0.18mm grouping perfectly stable, so every stroke lands with surgical consistency.

Key Features
3RL round liner in ultra-fine 0.18mm (04-series) — nano hair strokes and micro detail
Full stainless metal tip — stabilizes ultra-fine needles against flex
316 medical-grade stainless steel needles, 100% E.O gas sterilized

Material: metal

Best For
Nano brows / hyper-realistic hair strokes, fine eyeliner & lash enhancement, micro-detail PMU, small SMP touch-ups, corrective fine line work

Description
The 3RL- 0.18mm is BMX’s finest 3-needle configuration—specifically designed for Nano Brows, micro-hairstrokes, ultra-fine eyeliner, and PMU procedures requiring extreme realism and intricate detail. This anti-backflow (BF) version features a built-in membrane that prevents pigment from flowing back into the machine body, even during prolonged procedures using liquid pigments.
Fine needles require longer working times and a higher number of passes—making anti-backflow protection essential.

Description
The 3RL- 0.25mm (#08) is the fine-line specialist of permanent makeup. Three needles at the industry-standard fine diameter deliver the sweet spot of pigment flow, visibility, and control — the configuration behind most of the world's microblading-effect brows, classic eyeliner, and lip liner work.
This metal-tip (mt) version maximizes rigidity: the stainless tip keeps the 3-needle grouping perfectly stable through hundreds of strokes, so the last hair stroke is as crisp as the first.

Material: metal

Best For
Microblading-effect hair strokes , classic & shaded eyeliner , lip liner definition, beauty marks, fine SMP detail passes

For busy studios running back-to-back brow and eyeliner clients, the backflow version is the professional standard: same legendary stroke quality, with an extra barrier of protection between every client.

Material: backflow

Best For
High-volume brow & eyeliner studios, liquid pigment work, strict hygiene protocol environments, training academies

Description
The 5RL- 0.25mm (#08) is the Goldilocks of the BMX round liner range — not too fine, not too bold. Five needles in a circular grouping deposit soft, even saturation ideal for powder/ombré brows, lip blush shading, fuller eyeliner, and SMP density blending. Where a 3RL needs three passes, a 5RL needs one.
The metal-tip (mt) version keeps the wider 5-needle grouping perfectly stable — essential for even pigment distribution without patchiness.

Description
The 5RL - 0.25mm (#08) is the shading sweet spot: five needles lay down soft, even color for powder/ombré brows, lip blush, fuller eyeliner, and SMP density blending. This backflow (bf) version integrates a back-flow prev ention membrane — essential for shading work, which uses more pigment per session than any other PMU technique.
More pigment flow means more reason to protect your machine.

Description
The 7RL- 0.25mm (#08) is the widest round liner in the BMX range. Seven needles in circular formation bring medium-bold authority to SMP scalp density fills, full lip color packing, bold eyeliner, and areola restoration — jobs where a 5RL means doubled session time.
The metal-tip (mt) version is the professional choice at this width: the stainless tip keeps all seven needles evenly planted, so saturation stays consistent edge to edge with no patchy center.

Material: metal

Best For
SMP scalp density fills, full lip color packing, bold/shaded eyeliner, areola restoration, fast PMU coverage

more protection your machine needs.
