Found this ink to be quite good! Had tried other ‘sparkle” inks before and had used them for special occasion cards, etc. After reading some reviews on Dominant Industry pearl inks I bought this one and put it in my Noodler Ahab Flex (Navaho) from Wonder Pens. I had found the pen a bit “scratchy” and the upstroke would skip regularly. Not with this ink. It flows smooth no matter what. No scratchiness from the pen and the ink is so lovely when it dries. It looks like it is going on quite wet but does not bleed through my Leuchtturm. Within a few seconds it is dry and and that’s when the pearl lustre in the ink appears. Great ink for the price and so interesting on the page. Will definitely be getting a few more colours.
