Eleven Needles. One Curved Row. Expanded Possibilities for Linework and Shading.

Inkclaw 11FR Flat Round Tattoo Cartridges are designed for professional tattoo artists exploring geometric linework, defined edges, directional shading, and specialized tattoo techniques.

Featuring eleven needles arranged in a single-row Curved Flat configuration, the 11FR creates a distinctive linear contact pattern that differs from conventional Round Liners, Round Shaders, and Magnums.

Compared with smaller Flat Round configurations, its wider working profile offers greater versatility when developing structured patterns, graphic details, and directional textures.

• Hard-Edge Linework: Develop graphic outlines, directional marks, and distinctive linear effects.

• Blackwork & Graphic Tattoos: Build bold geometric patterns, structured shading, and high-contrast details.

Flat Round Needle Structure, Gauge & Taper

Eleven needles. One row. A distinctive working profile.

Unlike Round Shader needles arranged in a rounded grouping or conventional Magnums arranged in multiple rows, Inkclaw 11FR features eleven needles positioned in a single-row Curved Flat formation.

This specialized structure provides a broader linear contact profile than smaller Flat Round configurations, offering artists an alternative approach to geometric shapes, defined contours, and directional shading.

Manufactured with a #12 (0.35 mm) needle gauge and 3.5 mm taper, the 11FR combines an eleven-needle grouping with consistent needle-point geometry.

Needle arrangement, gauge, taper, and machine settings influence contact characteristics, pigment delivery, and working feel. The ideal setup depends on the artist's technique and desired visual effects.
