rOtring Isograph inchiostro pigmentato nero 23 ml per strumenti tecnici da disegno

Technical drawing ink that delivers crisp, permanent lines without clogging fine pen mechanisms. This rOtring black pigment ink, in a 23 ml bottle, provides dense, lightfast coverage that dries quickly on drafting film, vellum, and tracing paper. Its non-clogging, free-flowing formula keeps Isograph, Variant, and Varioscript pens ready for continuous work.

Advantages

Once dry, the ink is water-resistant, UV-resistant, and permanent, ensuring archival-quality documents.
