Yes, pens use real ink, although the composition of the ink can vary.
Pens utilize ink as their writing fluid. The specific type of ink depends on the type of pen:
- Ballpoint Pens: These pens use a thicker, oil-based ink.
- Rollerball Pens: These pens use a thinner, water-based ink, similar to that used in fountain pens.
- Fountain Pens: These pens use a liquid ink typically composed of dyes or pigments dissolved or suspended in a water-based solvent.
Therefore, while the viscosity and base may differ, pens definitively contain and use real ink.
