PITT Artist Pen

These black PITT artist pens contain pigmented India ink. It is extremely fade-resistant, smudge-proof, water-based (but water-proof when dry), pH neutral and has maximum light-fastness (7.8 Blue Wool Scale). Preliminary tests indicate that this pen writes well on B-72 base coat, dries quickly and may be top-coated with Paraloid B-72 in acetone without smearing. Testing is ongoing. The pen should be stored horizontally when not in use. Price each.
