“The pen casing is beautiful, I love it. Sadly, the ink cartridge ruins it for me. The 0.7mm refill is ridiculously thick, unnecessarily so. It holds up well on Tomoe River, Clairfontaine, and MD paper, but will bleed through everything else (stalogy and leuchtturm included). It also takes over five minutes to dry completely without smudging. Unfortunately, only 0.7mm refills are available, and there doesn't seem to be any viable alternatives that will fit the casing. It would be perfect if they made 0.3mm or 0.4mm refills!”
