Inlumino Heart Ink - Ballpoint Cartridges Saturated Ink - Box of 6

Why Saturated is different: Most ballpoint cartridges use oil-based ink that sits on top of the paper, can leave a greasy residue and dries out quickly even with ink left.
Inlumino Heart Ink – Saturated Ink is water-based, engineered for better flow & efficiency: it absorbs into the paper for cleaner, sharper lines, its more liquid formula reduces drying & clogging, it holds 3× more ink for extended sessions, and delivers brighter, bolder marks.

Ideal for dotwork & stippling, precise fineline practice and soft shading—on your actual cartridge tattoo machine. Machine-friendly, compatible up to 3.5 mm stroke, with a patented design (US Patent 12,109,836).

Why you’ll love them:

• Real-world feel with your own machine

• Fine control for dot density, whip/pepper shading & micro lettering
