Unlike most calligrapher markers whose tips wear down with use, resulting in inconsistent, increasingly heavy marks, the Pigma Calligrapher maintains its ability to continually create crisp, flowing lines and letterforms. The Pigma® Calligrapher™ is a unique, all-in-one, durable lettering art tool that produces crisp edges and sharp hairlines. This disposable pen has a hard nylon nib that withstands heavy pressure and constant use, and still provides a reliable, smooth ink flow from edge to edge. Pigma Calligrapher Pen 3ct Black
