An advanced alcohol-based ink formula that ensures rich color saturation and coverage with silky ink flow. The alcohol-based ink doesn't dissolve printed ink toner allowing for odorless vividly colored artwork on printed materials. The delivery of ink flow can be perfectly controlled to allow precision drawing. The ergonomically designed rectangular body resists rolling on work surfaces and provides a perfect grip that avoids smudges and smears. A specially designed safety cap stacks neatly and prevents damage to the nibs. Each marker can work with one of four replaceable nib options to achieve a wide range of strokes from fine lines to wide color fills. Extend the life of the marker with refill inks; or mix custom colors!
