Sakura Midnight Dusk Gelly Roll Gel Ink Pens. The creamy, smooth, opaque ink comes in bright, vivid colours that are luminous on white and black paper. Works like a paint pen on coloured papers, vellum, and photographs. Pigment-based ink is chemically stable, waterproof, fade-resistant, and archival quality. No feathering or bleed-through on most papers and no smearing once dry.
