Sakura Permapaque Fine Tip markers have a single round bullet tip thats great for signatures, fine details, monoline lettering, and drawing. Writes on wood, metal, plastic, glass, and ceramics.
Permapaques are safe, "no mess" opaque markers that offer maximum creative potential no need to shake or pump! Water-based pigment ink is odorless, non-toxic, and acid-free. Markers are quick-drying, wont bleed through most papers, and fade/water resistant when dry.
Pigment ink is permanent & archival for papers, however these markers are not permanent on all non-porous surfaces (plastic, metal, etc.) Test on a small area first to see if marks will rub/scratch off once dry. Not recommended for fabrics.
