Zig markers are double-ended, with two chisel nibs for calligraphy and lettering. Large nib is 5.0mm and the small nib is 2.0mm. The water-based pigment ink is photo-safe, waterproof, acid-free, odorless, xylene-free and lightfast.

These are more of a "craft" marker than a hardcore vandal tool, however many hand style masters love these for scripts and technical lettering. Especially good for handmade stickers and blackbooks.
