Namurataiseidou Calligraphy Brush, Fine Brush, Takachiho (Small)

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