The Faber-Castell Creative Studio Ocean Blue 160743 marker is a multi-surface permanent marker that adheres perfectly to glass, plastic, stone, metal, and cardboard. Developed with highly opaque water-based ink, it does not emit strong odors or bleed onto the paper, making it ready to draw with immediately. Thermal curing in an oven at 160ºC for 30 minutes provides water resistance to the pigment on hard surfaces. The deep and serene ocean blue tone is ideal for maritime illustrations, modern calligraphy, and personalizing objects.
