Pens & Markers

The pen makes the signature. The wrong choice — water-based ink on glossy stock, ballpoint on canvas, fading dye on archival prints — kills the signature within years. These are what professional signing-event runners hand to talent.

Sharpie fine point permanent marker
Sharpie Fine Point — Black
