5/5 stars for me personally. I am a bit of a pen enthusiast so many aspects about pens are critiqued & evaluated. Pen colour, ink color, exterior weight, shape, surface feel, amount of ink flow & very important is how it feels when writing. These have great ink flow size for a .7 pen. Not too thick that my small writing melts into each other, but not thin that makes colors hard to read. It is smooth, but not too smooth. Last long. Never have I had a glob of ink either when writing or if the pen had been sitting a while. Always pick up & write no hassle. Ticks all my boxes! Shame these are so hard to find/expensive. = (
