POSEIDON Professional Tattoo Cartridges 50-Pack – Assorted Sizes, 0.35" Universal Fit (3RL/5RL/7RL/9RL, 5RS/9RS, 9RM/11RM/15RM, 7M1)

Elevate your tattooing with POSEIDON Cartridges 50-Pack

Designed for both seasoned professionals and ambitious hobbyists, the POSEIDON 50-pack offers a broad spectrum of needle sizes in a single, ready-to-use collection. This variety supports a wide range of techniques, from precise line work to smooth shading, while maintaining consistent performance across the kit.

The pack includes 10 distinct sizes (5 needles of each size): 3RL, 5RL, 7RL, 9RL, 5RS, 9RS, 9RM, 11RM, 15RM, and 7M1. Note that RS-type needles correspond to Model #12, while all other needles are Model #10. The spiral nozzle design holds 30% more ink than standard needles and, when paired with laser-sharpened tips, helps deliver crisp lines and even shading for a professional finish.

What makes these cartridges reliable for real-world use

• Precision-engineered performance: Japanese-grade 316L stainless steel tips brazed to PVC cartridges; each needle is subjected to 12 quality checks for consistent sharpness and durability.
• Anti-leak safety system: Triple-seal design—elastic rubber membrane, spiral ink reservoir, UV-bonded nozzle—reduces blowouts and backflow risk.
• Universal compatibility: 0.35" cartridge base fits all major tattoo machine brands with plug-and-play simplicity; no calibration needed.

Sterile packaging and support you can rely on

• Sterile assurance: Each needle is sterilized by ethylene oxide gas and vacuum-packed to meet international hygiene standards.
• Poseidon Promise: 24-hour support response, lifetime defect replacement, and no-questions-asked refunds for your peace of mind.
