How do I love this ink? Let me count the ways. A drop dead blood red in every nib size I own (the "little black dress" of red inks). While the shimmer doesn't show in writing, it has a striking gold shimmer in swatches and a browned edge line. I can't wait to try it in a fat calligraphy pen. The flow is perfect - although the dry time is a bit slow, but I think that is true of most Herbin inks.
