10-Pack Ballpoint Pen Cartridges — Multi Color

WHAT'S IN THE BOX:

• 10 Ballpoint Cartridges (.5mm) — choose Original ink (2 each: Pink, Red, Purple, Blue, Green) or Saturated ink (2 each: Aqua, Yellow, Green, Purple, Pink)

HOW TO USE IT:
Insert into your own tattoo machine (up to 3.5mm stroke) and practice on paper over a soft backing — a foam pad, stacked paper, or fake skin underneath. Original ink runs up to 4 hours per cartridge at 4–7V for layering and depth; Saturated runs about 53 minutes per cartridge at 4V or lower for bold, high-flow color. (Paper use only — not for tattooing on real or fake skin. Machine not included.)

Five colors, your choice of flow — pick Original for gradients and depth, Saturated for bold and consistent.
