I'm addicted to Acme rollerballs! The designs, created by famous artists, are unique and beautiful. I've wanted this Roses one for a long time and finally gave in. I guess I have become, without consciously intending to, a collector. I have quite a few and love them all. The rollerball itself is easily replaced, and they write like a dream: smooth flow, no skipping, even width, and very clear lines. Service from the Pen Place is also outstanding.
