Chōeidō Calligraphy Brush, Chōhō Bokuyō

Purchased about five years ago.
Seems suitable for large characters with a mix of Kanji and Kana.
You can expect colorful and unique works, but the bristles are soft, so it requires some skill to write with.
Due to normal aging, the thin plastic that secured the product in the box has melted and adhered to the label. I believe this will not affect its use.
