I love this pen! I first purchased one of these pens while studying in Hong
Kong, and was impressed with the efficient, durable design. But when I got back
to the States, I couldn't find the pens or refills anywhere. I stumbled across
this site, and ordered a big box so I wouldn't run out again.
The tiny carbide steel ball (0.28 and 0.38 mm) means less ink is wasted compared
to the American Signo line. At the same time, it writes as smoothly as a regular
gel pen. My only regret is that I can't purchase them in bulk.
