Archival, water-resistant lines - thanks to Super Ink
Super Ink is described as permanent, fade-proof and water-resistant, engineered not to smudge when wet. That allows ink lines to remain stable when layered with wet media such as watercolour.

Precise control from ultra-fine to bold - with multi nib sizes 0.03mm to 1.2mm
The set includes a range of nib sizes spanning 0.03mm up to 1.2mm, enabling everything from ultra-fine detailing to thicker outlines. Steel protection around the nib helps maintain tip shape and accuracy.

Durable tips for stencil work - with steel-protected nibs
Nibs are equipped with steel protection to resist wear from repeated contact with stencils and templates. That physical shielding reduces deformation during heavy use.
Longer-lasting tips mean fewer replacements when regularly tracing or working through stencils, ideal for frequent studio or classroom work.
