This is my homemade locally sourced black walnut ink! I live in East Nashville TN, these are made from East Nashville black walnuts my neighbors let me forage for in their yards! This is made with intention and NO preservatives. Which means there WILL be a slight layer of mold on the top which DOES NOT effect the pigment, It is easily removed from the surface. This a natural product that will keep over time, black walnuts are naturally slightly acidic, which helps preserve the pigment. The color is an absolutely gorgeous shade of a cool brown. The Image with the price tag has a sample of the hue. It comes in an 8 ounce glass jar, sealed. Shipping is slightly more expensive due to the fragility of glass.
