Dynamic Grey Wash is a pre-dispersed ink blended from the original Dynamic black ink formula. The specific formulas come from countless tests and years of polling black and grey specific artists to gather a commonality in ratios for the perfect 4 bottle set. The ink was created using purest hospital-grade water, which is filtered, distilled and UV sterilized in Dynamic's facility, to ensure the #00 Mixing Solution in our washes is at the utmost purity and held to the highest standard. Witch hazel has also been added to this solution not only adds a visible smoothness to your work but also brings a soothing quality and feeling to your clients.
