Liquid sumi inks are economical, convenient and time saving as it eliminates the need for grinding.
This KF series is made from the same high-quality soot as Yasutomo's sumi ink sticks. The bottle opening is wide enough to load ink for most brushes, and its cap conveniently doubles as a brush rest. Dries with a slight sheen and absorbs into paper slightly.
The KY series inks dry to a matte finish. The 6 oz. and larger bottles have an easy-pouring spout.
When dried, KF series ink is more water-resistant that the KY series, which allows for unique glazing capabilities.
