Namurataiseidou Calligraphy Brush Wooden Scroll Hakuho (White Hair) No. 6

A good brush has four virtues: "Sharp," "Sai," "Round," and "Healthy." "Sharp": The tip is sharp and well-defined. "Sai": The tip is neatly trimmed and evenly aligned. "Round": The entire tip is a regular, conical shape with no cracks. "Healthy": Durable, strong, flexible, and resilient. Namura Taiseido calligraphy brushes possess these four virtues, and are individually crafted by artisans. After use: To prevent ink buildup at the base, which could lead to rot or breakage, rinse the ink off the tip with water, rubbing it with your hands.
