Kwadron Hybrid System Round Liner Tattoo Cartridges – 20pcs

Kwadron Hybrid System Round Liner Tattoo Cartridges - 20pcs

Kwadron Hybrid System Round Liner Tattoo Cartridges combine a tightly grouped RL arrangement with redesigned internal guidance. The range covers fine details, lettering, geometric work, everyday linework, and heavier traditional outlines.

Each box contains 20 cartridges in one selected size. The current lineup from Kwadron includes 12 configurations across 0.25mm (#8), 0.30mm (#10), and 0.35mm (#12) diameters. Every option uses Long Taper geometry.

The RL points converge toward a compact central working area.

Round Liner geometry

RL needles form a circular group with their tips brought together at the centre. Smaller counts create narrower marks. Adding more points increases the working width, while the selected diameter changes the character and visual weight.

A 25/9RLLT, for example, combines nine fine 0.25mm points. A 35/5RLLT uses fewer points, but each one has a larger 0.35mm diameter. Count and diameter should therefore be considered separately.

AirFlowTech and guided pigment delivery

AirFlowTech manages airflow around the tip during operation. It works with the internal pigment path to maintain delivery toward the grouped points during continuous linework.

Drip-Channel tip

The redesigned tip includes a Drip-Channel that gives pigment a defined route toward the working end. This design supports the flow system without changing the compact RL geometry.

New Stabilization Technology

The extended support system limits unwanted lateral movement inside the housing. Additional guidance closer to the tip helps the group remain aligned during both short details and longer strokes.

The internal shape also reduces friction around the moving assembly. Together, these features address movement and pigment delivery as separate parts of the same cartridge design.

Available configurations

The code identifies diameter, count, layout, and taper. In 30/7RLLT, "30" means 0.30mm, "7" is the number of points, "RL" identifies Round Liner, and "LT" means Long Taper.

Code Typical role
0.25mm (#8)
25/3RLLT Very fine details and narrow lines
25/5RLLT Fine work with slightly more presence
25/7RLLT Delicate contours with added width
25/9RLLT A broader group made from fine individual points
0.30mm (#10)
30/3RLLT Detailed general linework
30/5RLLT Balanced everyday outlines
30/7RLLT Medium-to-bold contours
30/9RLLT Stronger graphic marks
0.35mm (#12)
35/3RLLT A compact group with heavier individual points
35/5RLLT Defined medium outlines
35/7RLLT Bold traditional contours
35/9RLLT The broadest and heaviest option in the range

Choosing a size

Select 0.25mm for the finest character, 0.30mm for a balanced middle option, or 0.35mm for more visual weight. Then choose the count: 3RL stays narrow, 5RL adds versatility, 7RL creates a stronger contour, and 9RL provides the broadest working group.

Hybrid compared with standard Kwadron Round Liner

Both ranges use the same basic circular RL arrangement. Hybrid adds extended stabilization, a guided tip, AirFlowTech, and the Drip-Channel. The standard version remains available in a broader selection of counts, while Hybrid currently concentrates on 3RL, 5RL, 7RL, and 9RL across three diameters.

Compare the Hybrid construction with standard Kwadron Round Liner cartridges or the mixed Round Liner Essential Pack.
