Whether you're creating delicate details or stronger, more defined outlines, you can select the RL configuration that best matches the work you are doing.

Designed for Linework

Round Liner cartridges are commonly used for:

• Fine linework
• Clean outlines
• Bold outlines
• Lettering and script
• Small details
• Traditional tattooing
• Illustrative tattooing
• Geometric designs
• Line-based blackwork

The final result will depend on more than the cartridge alone. Gauge, grouping, machine settings, hand speed, needle depth, ink and individual tattooing technique all affect the finished line.

Choose Your Gauge

Flow Carts Red Label RL cartridges are available in:

04 • 06 • 08 • 10 • 12 Gauge

Gauge refers to the diameter of the individual needles within the cartridge.

Different gauges can be selected according to the type of linework and result you are looking to achieve.

Choose Your RL Grouping

Available Red Label RL groupings include:

03 • 05 • 07 • 09 • 11 • 14 • 18

The grouping number refers to the number of needles in the configuration.

Smaller groupings can be useful for finer detail, smaller lettering and tighter areas.

Medium groupings can be useful for general outlining and everyday tattooing.

Larger groupings can be useful for heavier outlines and bolder linework.

Your machine setup and tattooing technique will also affect the finished result.
