Pennonia Kékfény is my sheening ink. It’s not a super sheener as I think it’s nice to see the actual color of the ink as well. The name simply means Blue Light and was chosen partly because it’s a blue ink that shines and partly because it’s a jab at the old Hungarian TV show Kékfény which was about legendary crime cases.
Regarding shimmer powders: If you decide to add shimmer powder to your ink order please note that these inks may clog your pen or make it hard to clean. Only use shimmering inks if you are willing to accept the downsides that come with it. We recommend using dip pens or fountain pens that are easy to disassemble and clean thoroughly.
