PITT Brush Pens use India Ink that is acid-free, waterproof when dry, and odorless. The brush nib is long lasting and sturdy, and can be refreshed by simply removing the nib and turning it over to reveal a fresh point! They are perfect for all types of surfaces including canvas, fabric, wood, and ceramic, and they won’t bleed through paper like traditional markers.
