A walnut pen might not be exactly groundbreaking, but using the ground up shells for the coloring of resin might qualify as a little different. Walnut was used as dye for both hair and fabric for many years. Thanks to our mixer technology, we're able to suspend the walnut powder in the resin for a deep rich natural brown color. (With just a hint of sparkle of course!)
Note: Due to the nature of the walnut powder, even we can't get it to mix 100%. There will be some small pieces of walnut distributed throughout the resin. It doesn't impact machineability and is just the nature of a natural pigment like this.
