Eternal Green Concentrate is a dark, translucent green ink that leans toward Eternal Grass Green (E19), known for its use as a mixing base to create a variety of deep green tones for shading and blending in tattoos. It is a vegan, organic, and water-based ink, manufactured with a high pigment load for vibrant, long-lasting results. The ink is pre-dispersed, providing a smooth application and consistent flow rate.
