I found one of these pens in a pen store last year and fell in love. It's easy to write with but has the little angled tip that allows you to add a bit of flair without the fussiness and pretense of a fountain pen. I ordered these for both home and office and I have one always at the ready when I want to write a note in a birthday card or something else where a little style is called for.
This pen writes really rather remarkably well, at a cost that defies belief, particularly as it includes P&P all the way from Japan (but it arrived in what seemed the blink of an eyelid).
I love trying new pens, but this was a real eye-opener. It writes extremely smoothly and easily, and you can achieve almost calligraphic effects with minimal effort. It doesn't leak, drip or splutter, and the ink dries almost instantaneously. I am very happy to sign official documents with it (which is a bigger thing than it might appear at first sight; I have only ever used fountain pens hitherto), and will certainly buy more of these.
I can't say how long the ink will last, or how resilient the nib will prove, but at this price, for this truly remarkable writing quality, I have no hesitation at all in giving this 5 stars in terms of its price/quality ratio.
