We chose Teranishi Chemical Industry's Guitar ink series as the companion for our fountain pen for its 100 years of experience in ink making and the proven track record of reliability in terms of color, coloring, paper handling, and moderate drying speed.

Besides that, the shared belief of Teranishi Chemical has drawn us to cooperate with them. To carry out art education, the freedom of expressing oneself and cultivating a rich sense of emotion is what they valued.

As for our desires, to bring richness and enjoyment to people's lives throughout the world with products that combine art and practicality, striving to pass on and develop traditional craftsmanship to the next generation is what we as Wancher deeply value.
