I must be the minority I have the zebra sarasa vintage collection and I quite like writing with them though they are not my favorite. I don't like the 0.7 nib the 0.5 are better but thats my preference.Oh my god thank you, yes! I've hated these pens after giving into the hype and buying them a few months ago. It's such an irritating feel and not smooth at all. My usual go-to pen is either a Muji 0.38 or a Pilot rollerball V5 so I just assumed it was not the right type of pen for me, but Sarasa attempt was an unexpected let down lol.
My favourite are more the papermate ink joy and ive never owned the muji pens
