Pigma pens have a pigment-based, archival black ink. The nib is made of nylon and metal, featuring a 0.02 mm line width. It has a sturdy needle-point nib, allowing you to maintain a consistent, desired stroke size. Pigma’s inks are known for being rich and striking, without causing bleed throughs. Notably, Pigma pens are also traditionally used for manga drawing, professional illustration and watercolouring.
