Piranha Fineline Premium Cartridges were developed by Piranha Lab using a unique mould for each needle type, meaning every diameter has its own injection mould. This ensures a single-body cartridge with no joints or internal gaps, delivering absolute stability and millimetre precision even in the finest needles (from 0.18 mm). The result is a more stable, consistent, and reliable tool — a true extension of the artist’s hand.

Each Fineline needle mould is individually manufactured for its specific diameter (0.18 mm, 0.22 mm, or 0.25 mm). Unlike generic cartridges that share universal moulds, the individual mould eliminates microvibrations and misalignments, ensuring the needle remains perfectly centred. This technical detail is crucial for artists working with ultra-fine lines, where even the slightest deviation is visible to the naked eye.

The internal flow system was completely redesigned by Piranha Lab to ensure a continuous and controlled ink flow, even with ultra-fine needles. The inside of the cartridge features specific channels that regulate pigment entry and release, preventing blockages and ink interruptions — two of the main issues in fineline work. The elongated tip geometry also improves pigment retention and reduces the need for frequent refilling during tattooing.

The 0.18 mm needles offer the highest level of precision in the Piranha Fineline range. They are ideal for micro-realism, botanical work, delicate lettering, minimalist geometry, and detailed linework. The monolithic cartridge structure ensures that even ultra-fine needles remain perfectly aligned and vibration-free, allowing for consistent and uniform lines — even during long sessions.

Thickness: 0.18 mm | Configuration: 3RL / 5RL | Use: micro-realism, ultra-fine lines, extreme detail

Thickness: 0.22 mm | Configuration: 3RL / 5RL | Use: fine contour lines, botanical detail

Thickness: 0.25 mm | Configuration: 1RL / 3RL / 5RL | Use: delicate lines with slightly higher density

All needles feature a long taper (LT) — super sharp for smooth penetration and precise depth control.

The Fineline Premium Cartridges are ideal for styles that require absolute control and delicacy, such as: Fineline / Single Needle • Micro-realism and small portraits • Botanical and detailed floral work • Fine lettering and minimalist typography • Geometric and ornamental precision tattoos.

Yes. All Piranha Fineline Premium Cartridges include an internal safety membrane that prevents pigment, blood, or fluid backflow into the machine. This protection is essential to maintain hygiene and extend the durability of the equipment.

Each needle configuration is identified by colour-coded O-rings — a detail that allows immediate recognition of the needle type and diameter during the session. This colour system enables quick identification, speeds up cartridge changes, and helps artists maintain an organised and efficient workflow.

Thanks to their single-body monolithic construction and exclusive mould for each needle type, Piranha Fineline Cartridges offer up to 30% more stability in comparative vibration tests. This structural rigidity is essential for fineline styles, where even minimal oscillation can compromise the line and the final result. More stability means less skin trauma, cleaner lines, and greater comfort for the artist. It also preserves the needle and taper sharpness for longer on the skin, preventing tip damage and reducing the risk of harming the client’s skin.

Each cartridge is EO gas sterilised, individually packaged, and ready for single-use disposal. The packaging is designed to ensure total tip protection and absolute hygiene and safety until opening.

Yes. Piranha Fineline Premium Cartridges are universal and compatible with all machines that use the cartridge system.

The available range is exclusively for fine line or bugpin work and includes 1RL (Single Needle) in 0.25mm, 0.30mm, and 0.35mm thicknesses, as well as 3RL and 5RL, both available in 0.18mm, 0.22mm, and 0.25mm.

The development takes place at Piranha Lab, the industrial design and engineering department of Piranha Global, and the production of each component follows high manufacturing standards. Every detail is controlled to ensure absolute consistency from batch to batch.
