The Faber-Castell Creative Studio yellow neon marker provides fluid luminosity and a surprising glow-in-the-dark effect for crafts and illustration projects. Equipped with a durable fiber tip and highly opaque water-based ink, it adheres perfectly to glass, plastic, metal, stone, cardboard, and dark papers without bleeding. Its photoluminescent formula reacts to black light or darkness after being charged with natural or artificial light. The neon yellow tone delivers a fluorescent and radiant highlight to cards, drawings, and artistic projects.
