Wormhole Tattoo Cartridge Needles 50pcs Mixed Set

Wormhole Tattoo’s 50-piece assorted cartridge set provides a broad mix of standard round liners (RL) across sizes 3RL to 11RL. Each cartridge features a rubber anti-backflow membrane design to prevent ink from entering the tubes, a crucial feature for beginners who are still building control and consistency. Constructed from PVC and stainless steel, these cartridges balance durability with a safe profile for first-timers practicing basic strokes and shading transitions. The package is ideal for learners who want to explore different line weights without purchasing multiple single-size packs.
Key notes for beginners: start with classic rounds (3RL–5RL) to practice clean, even lines. Move to larger RL sizes (7RL–11RL) to study shading planning and how line width affects composition. Always inspect cartridges for integrity and ensure a clean, sterilized workflow before every session.
POSEIDON 50PCS Mixed Size Cartridges

The Poseidon 50-piece set combines a wide range of mixed sizes designed to suit beginners who are building foundational skills in lining and shading. The standards include multiple RL and RS configurations with an emphasis on sharpness and durability. A notable feature is the ability to store more ink through a unique needle design, which can help maintain consistent color saturation during longer practice sessions. The needles are made from PVC and stainless steel, and each cartridge is sterilized with an independent blister packaging, making hygiene a straightforward part of the learning process.
Recommendation for new artists: begin with smaller RLs (3RL–5RL) to develop steady hand control, then experiment with RS and RM variants to practice shading and rounded edges as confidence grows. The included packaging supports clean, single-use practice across multiple sessions.
Poseidon 50Pcs Mixed Size Cartridges with Membrane

This Poseidon collection emphasizes a hygienic one-time joint design and a durable stainless-steel construction to support stable ink flow. The kit includes 10 sizes with five cartridges per size, covering common RL and RS variants such as 3RL, 5RL, 7RL, 9RL, 5RS, and 9RS, among others. Each cartridge is EO-sterilized and packed in an individual blister, which aligns with standard beginner practice routines that prioritize safety and cleanliness. Ink flow is designed to be smooth, reducing the chance of dry strokes or blotching during early tattoo lines and light shading.
Learning takeaway: focus on single-pass lines using 3RL and 5RL to establish uniform line width, then progress to 7RL and 9RL for broader fills. Remember to maintain a consistent grip and steady hand while observing the membrane’s role in preventing backflow during longer passes.
Wormhole 20Pcs Mixed Sizes Cartridges

This smaller Wormhole kit covers essential rounds for lining and shading with a compact selection: 3RL, 5RL, 5RM, and 7RM. Anti-backflow design remains a core feature, with soft glue parts and a sealed packaging approach that supports safe transport and handling for beginners. The set is well-suited for short practice sessions and for artists who want to explore both line work and basic shading without committing to a full-size assortment.
Practical advice: use 3RL and 5RL to practice clean, consistent lines on practice skin, then try 5RM and 7RM to begin exploring even, soft shading. Always verify membrane integrity and ensure needles are stored in sterile conditions between uses.
50 Assorted Mixed Size Cartridges

This set aggregates multiple RL and RS configurations, including 5RL, 7RL, 9RL, 11RL, and 5RS, 9RS, plus longer taper options like 15M1 and 21M1 for broader shading options. All cartridges are sterilized by EO gas and individually sealed for single-use practicality. The universal compatibility note is important for beginners who may be using a range of rotary machines and want flexibility across devices. The varied sizes help learners experience how line weight and shading density affect composition in a controlled, repeatable way.
Application tip: for beginners, work with the 5RL and 7RL first to master consistent line weight, then introduce 9RL and 11RL for bolder outlines. Use the 5RS and 9RS to experiment with light shading and gradient effects on practice skin.
Buying Guide: Key Purchase Considerations For Beginners
- Needle configuration and sizes: Start with common rounds like 3RL–5RL for outlines, then include 7RL–9RL for broader shading. RS variants help with softer shading transitions crucial in beginner work.
- Membrane and backflow prevention: Choose cartridges with a reliable membrane design to reduce ink backflow, improving safety and reducing mess during practice.
- Material quality and sterilization: Look for cartridges made from medical-grade plastics and stainless steel. EO gas sterilization and individual packaging are strong indicators of hygiene and readiness for beginner use.
- Compatibility: Ensure the cartridges fit your tattoo pen or rotary machine. Most universal cartridges work with standard European and American pen interfaces, which is helpful for new artists experimenting with different devices.
- Practice suitability: Beginners should favor sets that include a mix of RL and RM sizes to practice both lining and shading. Zero-in on kits that offer a balance between practical coverage and safety features.
- Packaging and storage: Sealed, single-use packaging supports clean workflows and reduces cross-contamination risk during practice sessions.
In practice, a beginner should select a starter bundle that includes a core range of RL sizes (3RL–5RL) for lines, a couple of larger RLs (7RL–9RL) for shading, and a handful of RS or RM variants to explore soft transitions. Pairing a cartridge kit with a compatible beginner-friendly tattoo pen or wireless kit can further simplify learning by reducing setup complexity and maintenance concerns. Always follow manufacturer guidelines for hygiene and consumable rotation to sustain safe, responsible practice.
For learners evaluating options, consider the breadth of sizes, the presence of membranes to prevent backflow, and the overall fit with your current machine setup. A balanced mix supports progressive practice from precise lines to fuller shading while maintaining safety and ease of use.
Additional Notes On Safe Practice
Always work with clean surfaces, practice on skin simulants or practice skin, and follow local regulations on tattoo safety. Verify each cartridge’s sterilization status before use, and discard any cartridge showing signs of damage or leakage. Regularly inspect your equipment setup to ensure stable power delivery and consistent needle projection, which directly influence line quality and shading accuracy for beginners.
