TL;DR: Tattoo cartridges are pre-configured needle modules that simplify setup, improve hygiene, and cater to various tattooing styles. Choosing the right cartridge means considering factors like membrane type (for safety), needle configuration, groupings, and compatibility with your machine. This guide helps artists—beginners to pros—match the best cartridges to their style and experience.

Introduction

Cartridges have revolutionized modern tattooing. They’re faster to swap, safer to handle, and easier to use than traditional needles. But with so many brands, configurations, and buzzwords floating around, how do you pick the right one for your work?

 This guide covers:

• Cartridge configurations for lining, shading, packing, and realism
• Membrane vs. non-membrane systems
• Recommendations for artists at every skill level

What Are Tattoo Cartridges?

Tattoo cartridges are modular needle groupings encased in disposable plastic housings. Unlike traditional needles that need to be soldered and matched with grip tubes, cartridges are plug-and-play—designed to snap into compatible rotary pens and grips.

Why they’re popular:

• Faster needle changes
• More hygienic (especially with membrane systems)
• Ergonomically consistent

Key Cartridge Configurations

Round Liners (RL)

• Grouped in tight circles
• Ideal for crisp lines and detail work
• Sizes: 1RL to 14RL

Round Shaders (RS)

• Wider spacing between needle points
• Good for color blending and soft fills

Magnum Shaders (M1)

• Needles in two rows (staggered)
• Used for color packing, gradients, and black & grey

Curved Magnums (CM / SEM)

• Arched needle layout for smoother shading
• Less trauma than flat mags

Flat Cartridges (F)

• Single straight line of needles
• Used for bold lines or color transitions

Membrane vs. Non-Membrane Cartridges

Membrane Cartridges:

• Prevent ink and blood from entering the grip or motor
• Safer and more hygienic
• Required in many regulated studios

Non-Membrane Cartridges:

• Less expensive
• Shorter throw (can feel more responsive)
• Risk of backflow contamination

 Bottom Line: Go membrane unless you’re working on practice skins or using disposable grips.

Choosing Cartridges by Tattooing Style

• #10 diameter

Color Packing:
