Monotonic is a versatile ink-channel solution that expedites fountain pen testing, tuning, maintenance, and cleaning. Our gentle, handmade formula streamlines similar operations at the workshop and is compatible with all fountain pens. Containing zero dyes or pigments, Monotonic is designed with components of a standard fountain pen ink vehicle to leverage the utility of a writing backbone without the extra attention required to work around colorant.
Monotonic is built with a highly purified water diluent and a delicate mixture of humectant, lubricant, and preservative. The solution will safely air-dry after use or operate as the segue to a new ink while still damp with a minimal impact on performance and hue.
DOES NOT contain ammonia or bleach.
