I really like the KWZ gray plum. This actually fulfilled my desire for a gray ink that was dark enough to be used for business. The last gray ink I purchased was much too light. In my pen barrel which is clear and eyedroppered, the ink appears purple. When applying ink to paper you can see that the color is appropriately named Gray Plum. Being a lefty I like the fact that this ink dries very quickly. It flows nicely and is well behaved in my pen. This experience has encouraged me to try other KWZ ink options. Purchasing the ink from a great brick and mortar store like Truphae somehow seemed to increase the value of my purchase. What a nice store! If you’re in South Carolina and you like pens (especially fountain pens) and ink, check out Truphae.
