Fenris – professional tattoo cartridges

Fenris is a brand of tattoo cartridges created for artists who demand maximum precision, stability, and safety. Our premium needle cartridges combine advanced engineering with refined design, making them an ideal choice for both beginners and professional artists.

Fenris cartridges feature perfectly sharp needles, a medical-grade safety membrane, and a clear tip that provides full control and visibility. Precisely fitted tips reduce needle wobble, increasing comfort and accuracy.

Available in all popular configurations: Round Liner (RL), Round Shader (RS), Magnum (RM) — in the most popular sizes 0.25 / 0.30 / 0.35 mm and groupings from 1–49 (depending on the model).

High-quality workmanship makes Fenris cartridges fully compatible with all common pen-style machines and Cheyenne-type grips. This setup is perfect for outlining, shading, and filling—whatever your style or technique.

If you’re looking for tattoo cartridges that deliver consistent, reliable performance with maximum precision, choose Fenris.
