I want to buy a set of brushes for my grandfather who likes calligraphy, but I don't know how to match them. Do you have any knowledgeable friends to recommend them?

choose brushes with different materials and prices according to different needs. Small letters have the highest requirements for writing brushes. Generally speaking, it is more appropriate to choose pure frozen hair for howling or suffering from problems, and the pen tip is about 1.5~2 cm. If you write official script and seal script, you usually choose lamb hairbrush. Sheep hair brush is relatively durable and has a large amount of ink storage. Writing running script and regular script, generally choose doubled both brush brush, or wolf hair brush. The front is about 2.5 to 4 cm. I hope it helps you.
