I bought one of the Uni-ball Signo UM-151 .28 tip pens whilst visiting in Japan
last year, but didn't try it until I returned to England. It was brilliant -
fine smooth consistant line enabling me to get lots on a page when making notes.
When the ink ran out I found I just couldn't get the same pen in Britain and
hunted on the internet until, I found Jetpens.
I ordered both .28 + .38 tip pens and also refils - a little apprehensively as
they were to come from the USA. My order and dispatch were both acknowleged by
email and the items arrived safely within 10 days. They are absolutely identical
to the one I bought in Japan. I'm highly delighted.
