This product is a double-tipped marker pen that has both black ink and light gray ink. It is customary to use the gray color for occasions when offering condolences in Japan; however, for international consumers, this color may be useful for calligraphy and drawing activities.
What makes this product friendly to brush pen beginners is that its originally-developed elastomer tip allows them to write well-balanced letters with smaller uneven lines without exerting too much force on the pen. This function gives users a greater opportunity to write beautiful letters like a skilled calligrapher.
This product also includes a plate to help you write the letters neatly in a straight line.
