DarkLab Vertix Cartridges - 0.35mm Magnum Curved, Medium Taper, Box of 20

Consistent ink flow and precise needle control are critical during long shading sessions. The DarkLab Vertix Cartridges in 0.35 mm Magnum Curved Medium Taper are built for professional tattoo artists who need reliable performance for smooth blending, colour packing and realistic gradient work. Each box contains 20 disposable cartridges fitted with Japanese surgical steel needles and a transparent, detachable tip that gives you a clear view of ink flow throughout your session.

The internal tip geometry is designed to optimise ink saturation, meaning you spend less time dipping and more time working. DarkLab's proprietary dual side vents create a decompressing vacuum action that minimises spray and allows for a clean rinse when switching between shades. A secure low-tension membrane prevents ink from flowing back into your machine, reducing motor stress and long-term wear on your equipment.

The detachable tip also allows you to make slight needle position adjustments mid-session without swapping cartridges

most cartridge brands require a full swap to change needle depth. Every cartridge passes a two-step quality control process, combining automated inspection with human checks to ensure consistent needle grouping and membrane tension across the box.
