Pennonia Törökkék or Turkish Blue is our staple turquoise blue. The ink is what you would expect, a safe color for everyday use. In normal circumstance it doesn’t produce sheen however a little is possible on papers like Tomoe River Paper.
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.
