Seven Needles. Defined Outlines. Confident Linework.

Inkclaw Regular 7RL Round Liner Tattoo Cartridges are designed for professional tattoo artists seeking defined outlines, consistent linework, and greater coverage for medium-to-bold lining applications.

Featuring seven needles arranged in a regular Round Liner grouping, the 7RL provides a broader contact pattern than smaller 3RL and 5RL configurations, making it a versatile choice for structured contours, traditional outlines, and expressive tattoo designs.

Available in three needle gauges and two taper lengths, Inkclaw 7RL cartridges allow artists to select the needle geometry that complements their technique and preferred line characteristics.

Designed for Defined Linework

Stronger contours. Clear definition. Creative freedom.

• Traditional & Neo-Traditional Tattoos: Create prominent outlines, structured contours, and classic tattoo linework.

• Illustrative & Graphic Tattoos: Develop defined silhouettes, expressive shapes, and strong visual elements.

• Lettering & Script Tattoos: Build substantial lettering, decorative scripts, and clearly defined typography.

• Blackwork & Ornamental Tattoos: Create bold decorative lines, geometric patterns, and structured outlines.

• Japanese Tattooing: Develop defined contours, traditional motifs, and prominent linework within larger compositions.

Needle Gauge & Taper Options

The right needle geometry for stronger line definition.

Inkclaw Regular 7RL cartridges are available in three needle gauges:

• #08 (0.25 mm): A finer diameter for controlled outlines and detailed linework.

• #10 (0.30 mm): A versatile diameter for defined contours and everyday lining.

• #12 (0.35 mm): A larger diameter for more pronounced outlines and stronger line presence.

Two taper lengths—3.5 mm and 5.0 mm—offer additional flexibility in needle-point geometry and pigment delivery characteristics.

The regular seven-needle grouping provides a broader working profile while retaining the concentrated contact pattern associated with Round Liner needles.

The ideal gauge and taper combination depends on the artist's technique, equipment, and desired linework.
