Namurataiseidou Calligraphy Brush, Thick Brush, Special Selection Calligraphy Taisei No. 1

A good brush has four virtues: "Sharp," "Sei," "Circle," and "Ken." "Sharp": The tip is sharp and well-defined. "Sei": The tip is neatly shaped and even. "Circle": The entire tip is a regular, conical shape with no cracks. "Ken": Durable, strong, 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 ink off the tip with water, rubbing it gently with your hands.
