Blue Moon

Robert Oster Blue Moon is a vibrant mid-blue shimmer ink from the Shake 'N' Shimmy series, known for its striking shading from light aqua-turquoise to deep powdery blue, beautiful silver shimmer, and cinnamon sheen in pooling areas. It performs best on fountain pen-friendly papers like Rhodia and Tomoe River, offering razor-sharp strokes but requires thorough pen cleaning due to particulates. Ideal for enthusiasts seeking a celebratory, eye-catching ink for journaling or art rather than everyday office use.
